1) “America’s Most Wanted” season-opener, 9:02 p.m., Fox. Back in 1988, Fox was a mini-network, airing only two nights a week. It debuted “AMW,” with John Walsh (whose son was kidnapped and killed) profiling suspects. The show was canceled after 23 years, then revived often. Now it’s back, hosted by Walsh (shown here), 79, and his son Callahan.
2) “Extracted,” 8 p.m., Fox. Four people remain, struggling for survival while loved ones have the choice of extracting them. There’s a retired cop, a river guide, a loan officer and a wellness coach. Tonight, one will win $250,000.
3) “NCIS: Origins,” 10 p.m., CBS. A week from a riveting season-finale, this show has fresh crises. Wheeler, the unit chief, has trouble holding his job as his family struggles. And new events reflect the “Sandman” sniper in the series-opener. Now the team links with the FBI.
4) Mysteries, www.acorn.tv. Two shows offer interesting, movie-length tales. In the season-opener for New Zealand’s “Brokenwood Mysteries,” the fan of a fading rock band is found dead; suspects abound. In the season-finale of the British “Chelsea Detective,” kids pick the wrong car to steal: It’s the one with a scientist’s body in the trunk.
5) ALSO: From 8-10 p.m., there’s a live “American Idol,” revealing the top-14. And at10, PBS has an hour that fits the eve of Earth Day: “Water For Life” views three Latin Americans who fought government and corporate forces, to keep their local river water from being diverted.
