Skull-stomping violence cracks open this Brit psychodrama, which dips into the head of a shy delivery boy (the appealing Martin Compston) drifting through a lonely london lif𒀰e. He’s mourning an attack on his brother ( Neil Maskell) when an old friend he only vaguely remembers turns up on his doorstep.

‘Piggy&rs🃏quo; (Paul Anderson, ) takes him on a bloody, escalating mission of vengeance against a local gang. Fluidly lensed and unsettling for an hour, writer/director Kieron Hawk♑es’ debut thins out badly in the final third, leaving the charismatic Anderson to prop it up.
