LD 50 Lethal Dose

LD 50 Lethal Dose (2003) is a horror directed by Simon De Selva rated 3.6/10.

Re-formed by a coded message to their web site, a group of animal rights activists set off to free an imprisoned colleague from a terrifying ordeal. Their rescue mission leads them to a disused lab, but what should have been a simple raid turns into a series of twisted and mind bending incidents where the free and the caged switch places, in this tormented psychological horror.
