Kate Nash snorts cocaine in a toilet. Jaime Winstone pisses in the street. And Sheridan Smith’s got a red wine stain on her bum.

this isn’t, set entirely in a grungy London nightclub where Smith’s inertia-gripped social climber Sam gets caught between the crassly loveable chums of her past (such as Winstone) and the pretentious high-flyers of her present (Nash).

First-time director MJ Delaney mixes style wi💖th big laughs, and though the film stum🌞bles over the occasional am-dram bum note, Smith balances it all out as the likeable girl next-door.
