The Doyles show their sentimental side as they help Jake’s high school girlfriend run off into the sunset with her new husband, who’s running from both bad guys and good guys to just get away; Rose’s past comes back to haunt her in the form of her ex-con husband, while Leslie weighs whether or not she wants Jake in her future.

Jake sets out to find the true identity of a beautiful amnesiac who stumbles across his path and ends up fighting off her two stalkers; Martin Poole refuses to leave town and wreaks havoc in Rose and Mal’s relationship; and Leslie gives Jake the cold shoulder.

A grieving widow hires the Doyles to find out why her husband left a generous sum of money in his will to a woman she’s never heard of. Rose continues to battle with Martin over their divorce while Mal formulates a plan to get Poole out of their lives for good; and Leslie and Jake hit a comfortable stride as friends and colleagues - just as his divorce from Nikki becomes final.

When a dubious chip truck owner notices his truck is missing - along with his driver/best buddy - he cons Jake into taking the case; Martin really crosses a line with Rose and she takes matters into her own hands; and Jake’s divorce becomes final and he’s happy to tell Leslie that he’s now a free-agent. But Leslie’s just been bumped up the ladder with a promotion to Sergeant, and her eye is on the job, not Jake Doyle.

Jake and Mal are called to check into some death threats that have been made to a respected psychiatrist; an old "friend" from the past shows up and makes an interesting proposition to the Doyles; after Leslie's close call, Jake and Leslie find themselves struggling a little in their new romantic relationships.

The Doyles reluctantly take on a case from a dodgy "old friend" when he promises them a big payday; Jake and Allison encounter friction when their professional lives impose on their personal relationship; Jake gets an interesting job offer from an unlikely source.

Jake and Mal investigate a hit-and-run and encounter a slippery criminal couple; Rose has a run-in with familiar ghosts from her past; Des discovers that Tinny's trip to London didn't go as expected. Guest star: Shannon Tweed

Jake and Mal contend with a hit man.
