Guilt

In an Edinburgh cellar, two gunshots ring out. Across town, Max McCall is released from prison. These two events gradually converge as Max tries to rebuild his life, while new arrival Erin is trying to save hers.

When Roy Lynch rebuffs Max's efforts at a reconciliation, Max turns to Kenny for help - despite their troubled history. However, this is a newly confident Kenny, with a budding new relationship, and he provides Max with a tougher challenge than expected.

To help his daughter, Roy finally turns to Max and Kenny and forces them to help him. It appears that Max's fall from grace is complete - but he has a secret motivation to reveal.
