What is a mysterious stranger from Soho doing in Victor Division? John Watt would like to know, and keeps a close watch on him. Smith and Weir are heavily involved in the tracking down of money previously stolen in a mailbag robbery. Both events are triggered by a successful jail break.

Smith and Weir answer a call and find an abandoned baby. They bring it along to the station, where Inspector Dunn is in charge in Barlow's absence.
