Welcome to hell—a.k.a. Belle Reve, the prison with the highest mortality rate in the USA. Where the worst supervillains are kept and where they will do anything to get out—even join the super-secret, super-shady Task Force X.
Still including psychotic clown herself, Harley Quinn (Margot Robbie), the new squad is filled with new, but expendable, supervillains such as Bloodsport (Idris Elba), Peacemaker (John Cena), King Shark (Sylvester Stallone), Polka-Dot Man (David Dastmalchian), Savant (Michael Rooker), Ratcatcher 2 (Daniela Melchior), Javelin (Flula Borg), and Captain Boomerang (Jai Courtney).
Amanda Waller (Viola Davis) arms them heavily and drops them (literally) on the remote, enemy-infused island of Corto Maltese to save the world from destruction by taking down a giant kaiju known as Starro. Trekking through a jungle teeming with militant adversaries and guerrilla forces at every turn, the Squad is on a search-and-destroy mission with only Colonel Rick Flag on the ground to make them behave... and Amanda Waller's government techies in their ears, tracking their every movement. With explosive devices implanted at the base of their skull, one wrong move and they're dead (whether at the hands of their opponents, a teammate, or Waller herself). If anyone's laying down bets, the smart money is against them—all of them.
