3-Headed Shark Attack is a 2015 American direct-to-video independent action film developed by The Asylum and starring Danny Trejo, Karrueche Tran and Rob Van Dam.

A 3-headed great white shark attacks an atoll where a group of teenagers is partying, killing all of them except one, Mark, who was on a buoy while the rest of the teens were at the beach.

A group of activists touring the lab consisting of Greg, Ryan Bennett, Omar, Alison, and college graduate Maggie Peterson, who applied for a job at the facility, also escape.

The group attempts to warn them, but they are too late, as the shark consistently rams into the ship, knocking numerous people into the water where they are eaten.

The group realizes they can no longer stay due to the ship sinking and board the activists' boat with Stanley, Rosemarie, and Howard in tow.

Meanwhile, Maggie, Stanley, and Greg manage to attract the shark's attention by throwing garbage bags into the water.
