This season the hit romance reality series will feature its ninth edition with the lucky new Bachelorette – Desiree Hartsock — getting to know 25 fortunate men via a series of social gatherings and exotic, romantic dates, some in groups, some individually. She will introduce some of the men to her family and will visit their hometowns for a slice of their lives in an effort to determine the man with whom she is most compatible. 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 the big question is: After all of this, will she hand out her final rose? And if she does, will the final bachelor accept it and propose?

Hosted by Chris Harrison, “The Bachelorette” is a production of Next Entertainment in association with Warner Horizon Television.

“MOTIVE” – SPECIAL DEBUT ON TUESDAY, MAY 21 (10:01-11:00 p.m.), FOLLOWING THE FINALE OF “DANCING WITH THE STARS THE RESULTS SHOW” THAT NIGHT, BEFORE PREMIERING IN ITS REGULAR TIMESLOT ON THURSDAY, MAY 23 (9:00-10:00 p.m.)
When murder is committed, Angie Flynn, a loving, single mother and a damned good detective, along with her partner, Detective Oscar Vega, are on the case, looking for clues that will lead them to the killer. 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. These storylines are then further explored via stylized flashbacks that piece together the mysterious connection between these two characters and what drove the Killer to commit murder.

“Motive” stars Kristin Lehman (“The Killing,” “Judging Amy”) as Detective Angie Flynn, Louis Ferreira (“SGU Stargate Universe,” “Rookie Blue”) as Detective Oscar Vega, Lauren Holly (“NCIS,” “Chicago Hope,” “Picket Fences”) as Dr. Betty Rogers, Roger Cross (“24,” “Arrow”) as Staff Sergeant Boyd Bloom, Brendan Penny as Detective Brian Lucas and Cameron Bright (“The Twilight Saga: Breaking Dawn – Part 2”) as Manny Flynn.

A group of young and ambitious rookie cops continue to navigate the emotional trials and tribulations of their professional and personal lives. 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 fiancŽ, 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. Last season our officers got what they wanted and had to deal with the repercussions.

This year they will have to look change right in the eye and learn to adapt — leaving them with some big, bold choices to make. “Rookie Blue” stars Missy Peregrym as Andy McNally, Gregory Smith as Dov Epstein, Charlotte Sullivan as Gail Peck, Enuka Okuma as Traci Nash, Travis Milne as Chris Diaz, Peter Mooney as Nick Collins, Ben Bass as Sam Swarek, and this season introduces Priscilla Faia as Chloe Price and Rachael Ancheril as Marlo Cruz.
