Premise
Following a fight with Spider-Man's old foes, the Sinister Six, the Avengers battle a Venom Symbiote, which ends up possessing the Six and controlling their bodies. All seems well after they defeat the villains and apparently destroy the Symbiotes, but the Avengers' real problems only begin when a surviving fragment of the Symbiote infiltrates the Avengers Tower, duplicates itself and possesses most of the heroes one by one. Spider-Man, Phoenix Princess, Black Panther (the only members who are immune to the organisms' influence) and Stark (whose armor is taken over by the Symbiotes) now need to find a way to free their teammates and stop the Symbiotes' rampage.

Plot
Spider-Man is swinging around New York freely until he is ambushed by his old foes the Sinister Six (consisting of Scorpion, Electro, Kraven the Hunter, Vulture, Rhino and led by Doctor Octopus), who had just implanted a terminal bomb. The villains fight him until Spider-Man is joined in the fight by the Avengers (who remind him that because he is now on their team, he no longer needs to battle his foes alone ). While Spider-Man is allowed to defuse the bomb, the Avengers battle the Six and effortlessly defeat them. Just as Spider-man finishes defusing the bomb, Scorpion (against Doctor Octopus' orders) activates (what he believes to be) the second bomb, which turns out to be the container of a alien Symbiote. The organism duplicates itself and possesses the Six, turning them into mindless monstrous lifeforms.

The Symbiote-mutated Sinister Six goes for a rampage across the city until Spider-Man and the Avengers again battle the Six and defeat them before leaving them to be checked in by S.H.I.E.L.D. agents led by Commissioner George Stacy and Maria Hill. Unknown to the Avengers, a small fragment of the Symbiote follows them and latches itself onto Hawkeye's equipment. Back in the Avengers Tower, Peter is training with Captain America and Black Panther while Mary Jane is demonstrating her Wing-Protector (the source of her wings composed of Ultimatum, a hybrid metal made of Vibranium and Adamantium) to Stark, Captain Marvel, Wasp and Hawkeye. All seems like a calm day until Hawkeye starts feeling strange and begins to hear voices in his head. And just as he oddly ends up appearing to have developed spider-like powers, it turns out that he was possessed by the Symbiote fragment which hid in his equipment. The organism envelops and takes over his body, taking the form of a monstrous entity calling itself "Venom".

The Avengers battle the creature as Captain Marvel attempts to remove the Symbiote from Hawkeye, but only to be taken by the organism as well. The Symbiote duplicates itself and starts spreading across the Tower and infects the other Avengers (Captain America, Wasp, Hulk (in his form of Bruce Banner) and Black Widow. Thor attempts to fight back, but he is subdued and disarmed by the possessed Captain Marvel and possessed by one of the organisms. Stark forcibly ejects his Iron Man armor, which is taken over by the Symbiotes. Spider-Man, Phoenix Princess and Black Panther are the only ones who are not possessed due to Spider-Man and Phoenix Princess' Phoenix enhancements and Black Panther's Vibranium suit and Heart-Shaped Herb-powered veins protecting their bodies. The three take Stark to the lab, where they work to prepare a Vibranium-powered device designed by Spider-Man which will wipe out the Symbiotes and free their teammates. Just then, they overhear that the Symbiote-possessed Captain Marvel is heading straight to the S.H.I.E.L.D. Helicarrier, where Venom plans to expand itself into maximum levels.

Phoenix Princess gives chase and, after a fight on streets, manages to separate Captain Marvel from her Symbiote mutation. Trying to fight his Symbiote possession, Banner gets agitated enough to transform into the Hulk, burning down the symbiote in him in the progress as Thor manages to free himself when the Symbiote tries to grab Mjolnir. Hulk, Thor and Black Panther manage to buy Spider-Man and Stark time to finish and activate the device, which extinguishes most of the symbiotes and freeing Captain America, Black Widow and Wasp. Only the Symbiote in the Iron Man armor remains and Stark, donning the Mark 50 (a nanotech-powered version of his armor), takes it into a destructive fight which takes place outside the Tower. Stark manages to fend off the Symbiote by flying it towards the Sun to its destruction, ending its threat. Sometime later, the Avengers are shown relaxing in the Tower after repairing the damage done by the Symbiotes while Wasp is shown in her bath robes after 12 straight baths (which she took until she was relieved of disgust of her Symbiote mutation) before they are greeted by their other teammates (Ant-Man, Black Cat, Falcon, White Swan and Redwing), who were out for a mission with S.H.I.E.L.D.. Elsewhere, another surviving fragment of the Symbiote manages to survive and make its way to Eddie Brock, who was at the time throwing darts at a picture of J. Jonah Jameson. The organism hisses and smiles deviously and episode ends.
