In the opening scene, set in 1973, the Troubles in Northern Ireland result in the death of Collette's younger brother when they are children. The film jumps forward to 1993 London. After a failed bombing attack in London, Collette is arrested and offered a choice by an MI5 officer, Mac, who is assigned as her handler. Either she spends 25 years in jail, thus losing everything she loves, including her young son. Or, she becomes an informant for MI5, spying on her own family. Collette agrees to inform. In return, Mac offers her a new identity after working for MI5.
