Less than 30 miles off the coast of Florida is an island. And if you’re one of the few that get to see it… it’s likely you will never leave. This is San Tiburon. Home to beautiful white sandy shores, crystal-blue waters… and the world’s most dangerous maximum-security penitentiary. For 185 of the world’s most dangerous super-powered criminals, it is their final home. They will reside within these walls until their sentence is served… or they meet their end. There are no escapes. There are no bargains or compromises. There is only San Tiburon. San Tiburon Federal Correctional Institution has just received a new arrival — an extremely dangerous vigilante calling himself Payback who is hellbent on killing the prisoners inside. While the Assistant Warden deals with the repercussions of adding such a volatile new prisoner, the Warden makes an attractive offer to a new Captain of Violent Crime – a former military man named Jason Brody. And soon, the wheels are set in motion for an inevitable showdown between the men.
