"The 100" (9 p.m., The CW):
The sci-fi saga follows 100 teens who have been freed from a space station prison, but with a catch: They must go down and explore Earth, which was pretty much fried during a nuclear holocaust nearly a century ago. So does that mean there are no Starbucks left?
"Doll & Em" (10 p.m., HBO):
Real-life besties Emily Mortimer and Dolly Wells star in this semi-improvised six-part comedy series that explores female friendship in a painfully funny way. Mortimer's Em is a Hollywood actress ("News Room"), and Wells' Doll is her childhood pal, who comes to work for her as her personal assistant after a bad breakup. Much turmoils ensues.
"The Americans" (10 p.m., FX): We're pleased to report that Margo Martindale's Claudia returns to the series tonight, but Philip and Elizabeth (Matthew Rhys, Keri Russell) aren't exactly overjoyed. Elizabeth probably still wants a piece of her after that whole fake-kidnapping incident last season.
