Set in a post-apocalyptic 1950's, the Fitzroy hotel, a derelict submarine beached just off Margate, is the last place for a traditional British summer holiday. Bernard, the hotel's bellboy, cook, maintenance man and general dogsbody faces a constant battle to keep the decaying hotel airtight and afloat. But when he falls in love with the scheming femme-fatal Sonya, he is thrown into a web of lies, backstabbing and chaos. As his world implodes, Bernard must choose between the woman he things he loves and the hotel submarine keeping them all alive.
