Blending the gritty, fast pace of murder investigations with the warmth and chaos of family life, Caroline Quentin stars as Detective Janine Lewis, a woman with two challenging roles: a high pressured career heading a police team that probes Manchester's most gruesome crimes, and a single mum raising four children on her own. On the job, Janine Lewis deals with drive-by executions, decomposed bodies, and abducted children. At home, she interviews nannies, schedules parent-teacher conferences, and bolts breakfast on the run. Striving to balance the responsibilities of her career and the demands of her family, Lewis throws herself into every challenge with energy and passion - even when her professional and personal lives collide.
