This neo-gothic, teen-friendly thriller stars Hugh Bonneville, George MacKay and Kelly MacDonald, and practically everything worth saying about it amounts to a spoiler. What I can tell you is that Bonneville and MacDonald get most of the killer lines and that the film explores class warfare, colonialism and queer desire via a shonky script but also original and deliciously dark.
Toby (MacKay) and Jay (Percelle Ascott) are two graffiti writers (they prefer that term to graffiti artists). They inveigle themselves into penthouses and mansions, where they spray the walls with three insouciant words: I Came By.
