When they corner the suspect, the team learns he’s behind a series of deadly fires in the neighbourhood. Meanwhile Fire Captain Simon Griggs is forced to make a horrific choice – one that pushes him to the edge of revenge and suicide. Parker (Enrico Colantoni), wrestling with his own decision about his future on Team One must convince this broken man to live.
