They’ll do anything to get out. She’ll do anything to keep them in. When happily married Grace comes home early one night and catches her husband, Dominic, with another woman in the cabin at the bottom of their garden, she is shocked, angry, and most of all, hell-bent on revenge. That’s why she acts quickly, locking the pair in the cabin while she decides what she wants to do to them. While Dominic and his mistress desperately try to get free, Grace makes a plan on the outside, but it’s a plan that is formed based on her previous experiences. That’s because this might not be the first time Grace has done something like this… Who is the real villain? The cheating husband? Or the vengeful wife?
