Summary
The Titans team up with Aquaman, Mera and Aqualad to stop Ocean Master and Black Manta when they plan to lead the Trench on a relentless hunt for the Trident of Poseidon with the purpose of destroying Atlantis and sinking the surface world into the deep sea.

Plot
The Titans are enjoying their first morning together in beach, where Starfire learns with Barbara and Terra how to Surf. Unfourtunately, their day is interruptd when a group of sea monsters called the Trench trash their party, leading them to fight back.

The Titans battle the monsters until a massive sea tornado emerges and engulfs them. From the tornado come the Sea King Aquaman, who invites the Titans for a visit in his kingdom in Atlantis. There, the Titans also meet their comrade Aqualad and Aquaman's wife and queen Mera, who explains that the Trench were sent by Aquaman's wicked half-brother Ocean Master to keep the surface heroes occupied so that they would not stop him from his search for the Trident of Poseidon, a mystic artifact with the power to control the Oceans, and use it to destroy Atlantis and flood the world. The group is suddenly attacked by another swarm of Trench and, after the Titans and Aquaman defeat them, Barbara finds a small badge in one of the Trench with and dark S logo, confirming that Slade is also collaborating with Ocean Master and Manta.

Meanwhile, Ocean Master and Black Manta are contacted by Slade, who informs them that the Titans and Aquaman are working together to try to stop them. Ocean Master, presuming that the Titans are nothing to dangerous, decides to go on with his plan and dismiss Slade's warnings, much to the displeasure of both Slade and Manta. Using an map Wonder Woman gave Terra, the Titans are able to locate the Trident, which Aquaman decides that it must be destroyed for the sake of all life on both sea and surface dwellers, before they are confronted by Ocean Master. A battle between the heroes and the Trench issues as Barbara works to keep the Trident away the fight. Just as the Titans defeat most of the Trench, forcing the others to retreat, Ocean Master escapes defeat by Aquaman and Aqualad and chases Barbara, who avoids near death when she tricks the villain into breaking the Trident in two. The progress causes an violent hurricane and maelstrom.

As the maelstrom erupts and engulfs the Trench one by one, the Titans work to stay out of the chaotic storm as Nightwing manages to save Barbara from being engulfed. Ocean Master attempts to attack them, but is foiled by Cyborg and thrown towards the maelstrom where the villain is sealed away in the Trident's crystal, and the storm ends when it fully engulfs the last piece of the Trident which Ocean Master tried to save in the last second. Black Manta retreats to an unknown cave informing Slade that Ocean Master's plan has failed (as they both predicted). With Ocean Master banished, Aquaman, Mera and Aqualad thank the Titans for their help before they leave back to the surface, but not before Nightwing suggests Aquaman to have a reunion with the Justice League about Black Manta and Slade, to which the Sea King agrees. The Titans continue enjoying their party before they are approached by Mera, who did not forget about the promise she made to Terra, which was to "make the party more exciting". And the Titans are surprised when Mera summons a herd of Orca Whales for the young heroes to ride on them in the seas, which even Starfire finds pretty enjoyable.
