When Lee Manning is found dead in Montreal, his wife's world is thrown into a tailspin. With the ensuing investigation revealing more questions than answers, she suddenly finds herself under suspicion, and her life under surveillance.
Despite investigating garda Emer Byrne's suspicion of Sarah, both women continue to press for answers. Emer is convinced Gumbiner-Fischer is hiding something, while Sarah is increasingly driven to discover who is responsible for her husband's death.
With the case suddenly closed, Sarah is thrown into free-fall. She makes an unexpected discovery, proving Lee clearly knew something he shouldn't.
Armed with her new-found knowledge, Sarah attempts to blackmail Gumbiner-Fischer, whilst Emer risks her career in pursuit of the truth. By doing so, both unwittingly set in process a deadly chain of events that ends in tragedy.
Horrified by Hoffman's ruthlessness, Nulty capitulates, encouraging Emer to officially re-open the case and follow it through, no matter who might be exposed. And over lunch with her sister's ex-husband, Sarah discovers some answers may lie closer to home.
A leaked document and search warrant soon lead Sarah and Emer to the true horror Hoffman fought so hard to conceal, exposing a collusion and a cover-up striking deep into the heart of one of Ireland's most shameful histories.
