What if your dream house became your worst nightmare? Jess and her husband need a new start. So when the chance to buy a rambling old house in the Suffolk countryside comes up, they leap at it. But not everyone in Suffolk is welcoming. The locals know a secret about the Maple House, and soon, Jess realises they've made a huge mistake. Something bad happened in that house.

From acclaimed writer-director Gerard Johnson comes a psychological thriller that's dripping in sweat, tears, and testosterone. Muscle is the story of Simon, an unhappy, unambitious office worker whose life is gradually taken over by Terry, his new, very hands-on personal trainer who reveals himself to be more committed - and more dangerous - than Simon could have imagined.
