Republic of Doyle

The Doyles help a close family friend beat a manslaughter charge despite the fact that he refuses to defend himself; Jake’s relationship with his ex-wife, Nikki, is heating up when it should be cooling down – and Leslie might be the perfect distraction.

A new case gets Jake and Mal caught in the middle of a daylight-kidnapping gang, which they quickly discover is all just a game. The game takes a sinister turn when one of the players turns up dead, and it's up to the Doyle P.I. Agency to find the killer in a very real murder. Des practises his investigative skills by tailing Tinny and finds out some very disturbing information.

Sergeant Jake Doyle is assigned to protect a mob informant but when a mysterious group of men impede him, Jake finds the tables turned - himself the target of a manhunt.

The extended Doyle family shows up on the doorstep unannounced and in huge trouble, leaving Jake and Mal to tangle with some formidable gangsters from across the pond.

Jake's location is uncovered in the Season 5 premiere. Later, Tinny oversteps her bounds.

Jake must solve a case while facing the facts about Leslie; the Doyle's try to adjust.
