It’s the summer of 1978 and a scrappy 15-year-old boy (Daniel Huttlestone) from a broken home encounters first love and punk rock while striving to keep his skint family afloat.

This coming-of-age movie contains a jarring mishmash of moods, veering as it does between urban grit (rioting punks versus skins and rubbish on the streets) and whimsical comedy (the young hero driving his dad’s cab disguised as a woman to hide his age).

For all its flaws, however, the film’s underlying sweetness makes it hard to dislike.

Good, too, to see punk icon Joe Strummer – played with bolshie vim by Jonathan Rhys Myers – as the story’s unexpected fairy godfather.
