The Missing. Second season of this anthology series stars David Morrissey (The Walking Dead) and Keeley Hawes as the parents of a long-missing daughter whose lives again are turned upside down when Alice (Abigail Hardingham) returns. The case draws the attention of the first season's retired detective, Julien Baptiste, who thinks Alice may be able to help him find another missing girl.

Last Week Tonight with John Oliver. TV's best investigative-comedy show returns for a fourth season of using humor to illuminate underreported issues. He says he doesn't want it to be "all Trump, all the time." Here's hoping. 11 p.m. Sunday, HBO.
