NCIS / 8:00pm (13) While the NCIS team is investigating a hit-and-run incident, Jimmy Palmer (Brian Dietzen) risks his life by joining a perfect stranger standing on the dizzyingly high outside ledge of a building, in a desperate attempt to keep the man from committing suicide, in “Keep Going.” Spencer Treat Clark guest stars; Mark Harmon, Pauley Perrette, Sean Murray and Wilmer Valderrama also star.
Halt and Catch Fire / 9:00pm (AMC) 10:04pm (AMC) 4:38am (AMC) A new episode called “Nowhere Man” gives supporting player Toby Huss a welcome chance to shine as his character, John “Boz” Bosworth, reaches a breaking point under pressure from his faltering marriage and a sense that his personal relevance is vanishing. Elsewhere, Donna (Kerry Bishe) grapples with some mounting suspicions.
Running Wild With Bear Grylls / 10:00pm (4) Vanessa Hudgens (“Powerless,” “High School Musical”) likely gets into much more than she bargained for in this new episode, which almost turns out to be her own version of “Raiders of the Lost Ark.” She and adventurer Grylls land in the High Sierras after rappelling from a helicopter, then have to evade a cascade of boulders and survive an encounter with a rattlesnake. Climbing a volcano that supposedly is dormant is another of the challenges they face.
MOVIE “Illicit” / 10:00pm (BET) David Ramsey (“Arrow”) stars in this 2017 thriller as a nice-guy parole officer married to a beautiful ex-model (Shireen Crutchfield), a union that works nicely until she decides she wants to go back to work. Vivica A. Fox and Dean Cain also star.
Saturday Night Live / 11:29pm (4) Having had both “Sully” and “Inferno” on theater screens at the time, Tom Hanks marked his ninth turn as a guest host on the program with this episode from last October. The telecast also has definite star power in its musical guest: Lady Gaga.
