Let the back-stabbing begin. “Survivor” returns for a new season, starting with the gasp! - 500th episode of the series. Yeah, we can’t believe it either. 8 p.m., CBS.

The valiant struggle for freedom resumes on “Underground” as the emotionally powerful drama series returns for Season 2. Joining the cast is Aisha Hinds as Harriet Tubman, the fabled abolitionist who helped to rescue scores of slaves. 10 p.m., WGN America.

As “The Catch” launches its second season, Ben is forced to reckon with his criminal past while in jail. Meanwhile, Alice and her team try to come to terms with getting in bed with the bad guys. 10 p.m., ABC.

This could be fun: “MacGyver” does a crossover episode with “Hawaii Five-0.” It has Mac and the team heading to Oahu to aid in earthquake relief efforts and rescue government scientists trapped in a building. 8 p.m., CBS.

Sigh. Prepare to say farewell to Mystic Falls as “The Vampire Diaries” ends its eightseason run. Stefan and Damon must fight their greatest enemy in one last battle — and Elena (Nina Dobrev) returns. 9 p.m., The CW.
