When Conner Riley is convicted wrongly of money laundering for the IRA, his half brother Michael (George McCluskey) offers to help. During the exodus from Ireland, Connors wife Olivia (Janet Adams) and son David (Lucas Eisele) begin to find out that Uncle Michael has dark secrets about why he was disowned by his father. Michaels past is far darker than they realise when his former Provisional IRA commander Daniel O'Neil (Paul Dewdney) seeks revenge for his imprisonment and takes Olivia hostage and forces Michael into an illegal boxing match. Michael must face his past to save his brother's wife and child from Daniels sinister intentions.
