Lee (played by Lee Mack) is unburdened by ambition or drive, drifting from one ill-advised job to another, and living off the goodwill and generosity of his clean living Californian landlady Kate (Megan Dodds, "Spooks"). Whilst Kate is determined to push Lee into making something of his life, uptight accountant Tim (fellow BAFTA winner and Stand-up, Tim Vine) struggles to get over his break-up with Kate and cope with her rapidly blossoming friendship with Lee.
