S5E1 The Wrong Man

Toby and Dev delve into a string of murders linked to a serial killer who ominously places live snakes beside his victims, reminiscent of a previously apprehended criminal that Michelle had successfully convicted. As Michelle attempts to relish her maternity leave with her husband Adam and their newborn daughter, her professional integrity is challenged when questions arise about a potentially incorrect arrest. This prompts her to return to the IIB to defend her reputation and confront the implications of her past work.
