The future of a south London crime family hangs in the balance. Mick Roman (Gary Webster), the cool head controlling a viper’s nest of warring egos, is gravely ill. But the question of succession in the family business (mostly drugs, some violence, lots of shouting) is hotly contested. Mick’s son Jimmy (Charlie Clapham) assumes he’s a cert, but his adopted brother Henry (Michael Head, who also directs) disagrees. And that’s before you factor in the treacherous women of the Roman family. This crime comedy has plenty of energy, as expected from a film that seems to be largely powered by cocaine, but it’s erratic and rather grating.
