Four applicants, with their own hidden agendas, are accepted by a mysterious corporation to participate in a medical experiment at an isolated testing facility. With no instructions and no supplies, the human lab rats must fend for themselves and figure out what part of the experiment each one is playing.
When the corporation becomes aware that a pregnant intruder has infiltrated the facility, they send in armored guards to clean up the mess. However, loyalties are tested when the guards learn the truth about the experiments and begin to turn on the corporation.
An intensely visceral thrill-ride in the tradition of REC, The Crazies and the Resident Evil series, Rancid is a blood-dripping gurney ride through the darkest corridors of hell.
