Ld 50 lethal dose
LD 50 Lethal Dose was a 2003 horror film directed by Simon De Selva, produced by Alistair MacLean-Clark and Basil Stephens and written by Matthew McGuchan. A group of animal rights activists set off to free an imprisoned colleague from a terrifying ordeal but their rescue mission turns into a series of twisted and mind bending incidents. Starring Tom Hardy, Katharine Towne and Melanie Brown.
Animal activists break into an animal research facility, when Gary (McCall) gets caught in a bear trap. Unable to free Gary, the rest of the group flees, leaving Gary to take the blame. A year later, the group has since disbanded until an encrypted e-mail from Gary arrives asking for help. Danny (Bill), who has been visiting Gary in prison, tells the group that Gary has traded his body for experiments in exchange for a reduced sentence.
The group, still stricken by guilt one year later, eagerly reunites to rescue Gary. They also pick up two new recruits — a stoner and an ex-Marine. At the remote lab where Gary is being kept, the group discovers the place abandoned, and soon finds themselves locked in a subterranean level full of labyrinthine hallways and experiment chambers. They also discover that a powerful electrical force is stalking them, and it has full control of the complex. The force plays havoc with the would-be rescuers, turning their righteous cause into a death trap. They must work together to outsmart and defeat the unseen evil.
