Polly Maberly

We first meet estate agent Natasha (Polly Maberly, Muscle) as she's having a wisdom tooth pulled out in excruciating close-up before she bolts from the dentist without paying. This sets the feverish tempo for the pain and pressure of the rest of the film. On the surface, she runs a successful business with confidence and charm, but her finances are spiralling and her creditors growing restless.

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.
