Keeper

Liz (Tatiana Maslany) heads into the wilderness with her doctor boyfriend Malcolm for a weekend of fun and frolicking. He has a rather more sophisticated residence than the usual cabin in the woods, and he also has a cousin who lives next door but is assured that he won’t bother them on their getaway. Everything seems to be going fine, they’ve even got a chocolate cake left by the caretaker, but when he has to go back into the city for a medical emergency and leave her alone for the day - well, things start going bump in the day. Is it the cake, or an ancient evil lurking in the woods that reveals the cabin's horrifying secrets?
