Nick and Ben are set on taking down Inspector Elise Roberge in order to avenge the brutal murder of Nick's sister and Ben's lover, Amelie.
Ben and Nick seek justice for a raped prostitute and encounter someone they both never thought they'd see again.
The squad escapes to a cottage for a weekend getaway, but too much drinking and close quarters have a detrimental effect. Meanwhile, Nick's concern for Ben increases after his partner gets a troublesome call from Internal Affairs; and Ben makes a bold decision that could put his career at risk.
In the aftermath of tragedy, the patrollers of 19 struggle to find their footing. Ben tries his best to keep the moral clarity he found at the cottage; Nick realizes what he wants in his life; Dulac loses control on the job; and Audrey meets a doctor.
Ben's troubles become public and Nick faces a crisis with his mother.
The full moon brings out the loonies in the form of a snow plow, maple syrup, Bambi in a box and a cello player gone cold.
