At the end of the journey, filled with drama and surprises against the backdrop of spectacular international settings and featuring innovative twists and special guest stars, the Bachelorette may quite possibly have found true love.

But "Motive" turns the tried-and-true crime drama formula on its head by indentifying the Killer and Victim at the beginning of each episode.

After three years on the job, these rookies are well on their way to becoming experienced officers, but at what cost? It's been six months since Andy McNally and Nick Collins left for their undercover operation. We return to 15 Division with them - and quickly realize that everything seems to have changed. But that's what being a cop is: adjusting to new situations, rolling with the punches. Change is constant, and if you don't adapt, you're left behind. So when Andy returns to find that Sam Swarek is now a Detective and that he's moved on, both professionally and personally, she's going to have to figure out how to deal with it. Meanwhile, Dov's life gets awkward when a one-night stand with Frank's goddaughter becomes more complicated; Chris is torn between staying at 15 Division and moving his new family back to his smaller, safer hometown; Traci is learning to work with new detective Swarek, while trying to move on from the loss of her fiancé, Jerry Barber; And although Nick and Gail have cemented their relationship, Nick can't seem to shed the feeling that all is not right between them.
