Gangland boss Zander Finn is so sickened by the brutal murder of his son in a Paisley pub, he decides to change his life. Following the advice of his priest and mentor, he moves clandestinely to London and becomes an ambulance driver. But when his old second-in-command Malky Maloney tracks him down on a London street, Finn knows he must return. Both his real family and his crime family face an existential threat from Albanian mobsters determined to take control of the Scottish underworld. Under the watchful eye of his charismatic mother, he must try to look after his lovelorn younger daughter and her older sister who is pregnant to his old enemy Joe Mannion’s son. His estranged wife, who has more than just a business relationship with Mannion, and his remaining son, crippled while serving in Afghanistan also require his attention. But most of all, he must take back what is his. Facing the forces of law and order under Detective Chief Superintendent Amelia Langley, a ruthless gang of Albanians and a beautiful but deadly Italian woman, Zander Finn struggles for survival in a rollercoaster ride of brutality, tenderness, misplaced loyalties and the utterly unexpected. The path to redemption is a perilous one, and it begins to look like Finn should have stayed in London.
