When Elena attends an underground warehouse party with her friends, she finds herself caught in a nightmarish trap where the revelers are mowed, sliced and crushed to death by a macabre series of contraptions operated by a masked psychopath. When the grisly massacre is over, Elena is the only survivor, but before she can escape she is transported to an unknown location. Fortunately for Elena, one man, Arkin, knows exactly where she’s headed. Elena’s wealthy father hires a crack team of mercenaries to force Arkin to lead them to the killer’s lair, but even these hardened warriors are not prepared for what they encounter.
