Led by the irascible Cannon (Simon Lyndon) a motley band of rehab patients await release. One of them, a young man named Miles (Matt Callan), hatches a plan; when he's released he will ride a bicycle cross country to his family home. Using the dubious skills acquired from a lifetime on the wrong side of the tracks, the other men decide to help. Despite a lifetime of failure and flint-hard cynicism, Cannon agrees to help but he knows the world can be a cruel place. In the aftermath of Miles' quest, Cannon is forced to find his courage.
