When four old school friends decide to make some easy money, they pick the wrong target. Very wrong. Robbing a small supermarket on a Manchester estate looks easy - but with one of them wounded and a dead body on their hands, could things get worse? They could. The supermarket is merely the front for something bigger. The friends are small fish who have unwittingly plunged into a very big pond and now they are swimming with the great white sharks of the criminal underworld.
