Moment of Surrender (2) (S21E02)

Nikki becomes increasingly suspicious of David Cannon when she finds blood in the trunk of his car. With Thomas by her side, she decides to collect samples for analysis, wondering if it could be connected to Sally Vaughn. At the same time, the revelation of a body linked to a murder case from sixteen years ago brings attention to three individuals who attended the same school. Emilia Fox leads the cast, alongside Julian Rhind-Tutt and Alex Macqueen.
