Keeley Hawes stars as Julie, a menopausal assassin living a quiet life in Greece, until her handler calls her back into action after a 10-year retirement. Her son Edward (Freddie Highmore), visiting for the first time in four years, discovers a fortune in his account, leading to family tensions and revelations. The series follows Julie as she navigates a complex plot involving a new handler, a deadly sniper attack, and a desperate attempt to uncover the truth behind her targeted status. The story also involves a Dutch man, Jasper (David Dencik), imprisoned in Libya, who possesses incriminating information; and Marie (Gina Gershon), a mysterious woman in London who reveals a surprising family connection.

The series interweaves multiple plotlines—including a yacht commandeering, a Libyan prison escape, and a London art class—that build to a suspenseful climax. The cast includes Shalom Brune-Franklin, Devon Terrell, Alan Dale, Jack Davenport, and Gerald Kyd.

Impact Statement: The show's success will likely depend on audience reception to its unique premise and blend of action, humor, and family drama.
