Plot
In 1988, following his mother's death, a young Peter Quill is abducted from Earth by the Ravagers, a group of space pirates led by Yondu Udonta. Twenty-six years later on the planet Morag, Quill steals an orb but is attacked by Korath, a subordinate to the fanatical Kree, Ronan. Although Quill escapes with the orb, Yondu discovers his theft and issues a bounty for his capture, while Ronan sends the assassin Gamora after the orb.

When Quill attempts to sell the orb on Xandar, capital of the Nova Empire, Gamora ambushes him and steals it. A fight ensues, drawing in a pair of bounty hunters: the genetically and cybernetically modified raccoon Rocket, and the tree-like humanoid Groot. Nova Corps officers capture the four, detaining them in the Kyln. A powerful inmate there, Drax, attempts to kill Gamora due to her association with Ronan, who killed his family. Quill convinces Drax that Gamora can bring Ronan to him, though Gamora reveals that she has betrayed Ronan, unwilling to let him use the orb's power. Learning that Gamora has a buyer for the orb, Quill, Rocket, Groot, and Drax work with her to escape the Kyln in Quill's ship, the Milano.

Ronan meets with Gamora's adoptive father, Thanos, to discuss her betrayal. Quill's group flee to Knowhere, a remote criminal outpost in space built in the giant severed head of a Celestial. A drunken Drax summons Ronan while the rest of the group meet Gamora's contact, the collector Taneleer Tivan. Tivan opens the orb, revealing an Infinity Stone, an item of immeasurable power that destroys all but the most powerful beings who wield it. Tivan's tormented assistant Carina grabs the Stone, triggering an explosion that engulfs Tivan's archive.

Ronan arrives and easily defeats Drax, while the others flee by ship, pursued by Ronan's followers and Gamora's adoptive sister Nebula. Nebula destroys Gamora's ship, leaving her floating in space, and Ronan's fighters capture the orb. Quill contacts Yondu before following Gamora into space, giving her his helmet to survive; Yondu arrives and retrieves the pair. Rocket, Drax, and Groot threaten to attack Yondu's ship to rescue them, but Quill negotiates a truce, promising the orb to Yondu. Quill's group agrees that facing Ronan means certain death, but that they cannot let him use the Infinity Stone to destroy the galaxy. On Ronan's flagship, the Dark Aster, Ronan embeds the Stone in his warhammer, taking its power for himself. He contacts Thanos, threatening to kill him after first destroying Xandar; hateful of her adoptive father, Nebula allies with Ronan.

The Ravagers and Quill's group join with the Nova Corps to confront the Dark Aster at Xandar, with Quill's group breaching the Dark Aster with the Milano. Ronan uses his empowered warhammer to destroy the Nova Corps fleet. Gamora fights and defeats Nebula, who then escapes, but the group find themselves outmatched by Ronan's power until Rocket crashes a Ravager ship through the Dark Aster. The damaged Dark Aster crash-lands on Xandar, with Groot sacrificing himself to shield the group. Ronan emerges from the wreck and prepares to destroy Xandar, but Quill distracts him, allowing Drax and Rocket to destroy Ronan's warhammer. Quill grabs the freed Stone, and with Gamora, Drax, and Rocket sharing its burden, they use it to destroy Ronan.

In the aftermath, Quill tricks Yondu into taking a container supposedly containing the Stone, and gives the real Stone to the Nova Corps. As the Ravagers leave Xandar, Yondu remarks that it turned out well that they did not deliver Quill to his father per their contract. Quill's group, now known as the Guardians of the Galaxy, have their criminal records expunged, and Quill learns that he is only half-human, his father being part of an ancient, unknown species. Quill finally opens the last present he received from his mother: a cassette tape filled with her favorite songs. The Guardians leave in the rebuilt Milano and fly to the Sovereigns' planet along with a sapling cut from Groot. Ayesha, leader of the Sovereign race, has the Guardians protect valuable batteries from an inter-dimensional monster in exchange for Nebula, who was caught attempting to steal the batteries. After Rocket steals some for himself, the Sovereign attacks the Guardians' ship with a fleet of drones. These are destroyed by a mysterious figure, and the Guardians crash-land on a nearby planet. There, this figure reveals himself as Quill's father, Ego, and invites Quill, Gamora, and Drax to his home planet. Rocket and Groot remain behind to repair the ship and guard Nebula.

Ayesha hires Yondu and his crew, who have been exiled from the greater Ravager community for child trafficking, to recapture the Guardians. They capture Rocket, but when Yondu hesitates to turn over Quill, whom he raised, his lieutenant Taserface leads a mutiny with help from Nebula. Taserface imprisons Rocket and Yondu aboard the latter's ship and executes his loyalists by releasing them into space. Nebula leaves to find and kill Gamora, whom she blames for the torture inflicted on her by their father: Thanos. While imprisoned, Rocket and Yondu bond. Groot and Kraglin, a remaining Yondu loyalist, free Rocket and Yondu, and they destroy the ship and its crew as they escape, though not before Taserface warns the Sovereign before getting killed himself.

Ego, a god-like Celestial that manipulated the matter around its consciousness to form this "home" planet, explains that it projected a humanoid guise to travel the universe and discover a purpose, eventually falling in love with Quill's mother Meredith. Ego hired Yondu to collect the young Quill after Meredith's death, but the boy was never delivered and Ego has been searching for him ever since. He teaches Quill to manipulate Celestial power. Nebula arrives at Ego's planet and tries to kill Gamora, but the pair reach an uneasy alliance when they discover a cavern filled with skeletal remains. Ego reveals to Quill that in his travels, he planted seedlings on thousands of worlds which can terraform them into new extensions of himself, but they can only be activated by the power of two Celestials. To that end, he impregnated countless women and hired Yondu to collect the children, but killed them all when they failed to access the Celestial power. Under Ego's influence, Quill helps him activate the seedlings, which begin to consume every world, but Quill fights back when Ego reveals that he gave Meredith the tumour that killed her due to the distraction she posed.

Mantis, Ego's naïve empath servant, grows close to Drax and warns him of Ego's plan. Gamora and Nebula also learn of the plan as Rocket, Yondu, Groot, and Kraglin arrive. As they come under attack from the Sovereign's drones, the reunited Guardians find Ego's brain at the planet's core. Rocket makes a bomb using the stolen batteries, which Groot plants on the brain. Quill fights Ego with his newfound Celestial powers to distract him long enough for the other Guardians and Mantis to escape. The bomb then explodes, killing Ego and disintegrating the planet. Yondu then sacrifices himself to save Quill, who realizes that the reason Yondu kept him was to spare him from the fate of Ego's other progeny, and that Yondu was Quill's true "daddy". Having reconciled with Gamora, Nebula still chooses to leave and resume her quest to kill Thanos by herself. The Guardians hold a funeral for Yondu, which is attended by Kraglin and dozens of Ravager ships, acknowledging Yondu's sacrifice and accepting him as a Ravager again.

In the film's epilogue (a series of five mid-credit scenes and one post-credits scene), Kraglin takes up Yondu's telekinetic arrow and control-fin; Ravager leader Stakar Ogord reunites with his ex-teammates; Groot has grown into a teenager; Ayesha creates a new artificial being with whom she plans to destroy the Guardians, naming him Adam; and a group of uninterested Watchers abandon their informant, who is discussing his experiences on Earth, and Tivan sits in his destroyed archive with two of his living exhibits: a canine cosmonaut and an anthropomorphic duck.
