Discovering a lapsed compensation claim for asbestosis, Junior resolves to pursue the case, encountering the young, ambitious lawyer Nicola Blyth who tells him he must produce a witness to testify on his father's behalf. Beneath Junior's altruism lies an uncomfortable truth. In debt and on the run from wealthy businessman, John Doran, following a disastrous loss at the poker table, Junior's only hope is to get his hands on his father's settlement. But hope, like luck, is in short supply. As father and son set out to find the witness, suspicion turns to torment as Robert learns of his son's motives and the true cost of Junior's betrayal is revealed.
