The 100

The sci-fi series calls it a wrap with a series finale fittingly titled “The Last War,” as Clarke (Eliza Taylor) and her friends arrive at their final decisive battle after almost incalculable fighting and loss. What remains to be seen, however, is a big question: Does humanity really deserve something greater? Lindsey Morgan, pictured, Bob Morley, Marie Avgeropoulos, Richard Harmon, Shannon Kook, JR Bourne, Shelby Flannery and Chuku Modu also are featured.

Blood on the Wall Journalists-turned-filmmakers Sebastian Junger and Nick Quested turn their cameras on Central America to explore the widespread corruption that is both accelerating and impeding migration of refugees fleeing the region for the relative safety of Mexico. Using candid first-person accounts from migrants on the road, farmers, security enforcers, journalists and politicians, the film chronicles how traffickers, corrupt elected officials and canny business interests have seized wealth and power, leaving everyday citizens to fight for survival. The situation has turned Acapulco from a tourism hot spot into one of the world’s murder capitals.

Jay Leno’s Garage

Jay throws caution to the wind as he jumps headfirst into some of the most dangerous and underappreciated automotive jobs in the world in the new episode “America’s Toughest: Unsung Heroes.” One of his guests, Martha Stewart — who knows a thing or two about growing up in a working-class family herself — shows off Edsel “Son-of-Henry” Ford’s Maine estate and takes Jay on a ride in her pristine Edsel wagon.

Archer

A new episode called “Robot Factory” finds Archer (voice of H. Jon Benjamin) and his associates teaming up with past nemesis/sometimes frenemy Barry (voice of recurring guest star Dave Willis) to stop a veritable army of Barrys from turning the entire world population into Barrys. We have a hunch this is probably a Barry, Barry good episode. The voice cast also includes Aisha Tyler, Jessica Walter, Chris Parnell, Judy Greer and Amber Nash.
