As couples go, investment banker Antonia (Rebecca Calder) and out-of-work actor Max (Jack Gordon) make an unlikely pair. She’s posh, rich, and ambitious; he’s struggling, scruffy and a bit of a slouch.

When he moves into her sleek London townhouse, their relationship couldn’t be more out of sync. What can he do to earn her trust and how far should he go to prove his love?

Writer-director Martin Stitt’s low-budget debut film requires patience from the viewer. Give it time, though, and this claustrophobic two-hander proves a compelling mix of psychological drama and slow-burning thriller.

With the action entirely confined to Antonia’s house, the film will be too airless for some tastes but, as it goes on, the characters reveal unexpected sides and both actors do fine jobs, with Calder particularly good as the City ice queen who turns out to be all too brittle.
