Backstreet's back -- to kill zombies.

Nick Carter has united members of his own boy-band, the Backstreet Boys, along with guys from *NSYNC, 98 Degrees and O-Town for "Dead 7," a post-apocalyptic zombie western set to debut on the Syfy network April 1, 2016.

The made-for-TV movie, from the people that made the "Sharknado" franchise, was co-produced by Carter with a script based on his idea about "a reluctant hero (Carter) destined to unite this group of unlikely heroes in the ultimate zombie showdown."

Along with Carter, "Dead 7" features the Backstreet Boys' AJ McLean and Howie Dorough, *NSYNC's Joey Fatone and Chris Kirkpatrick, 98 Degrees' Jeff Timmons and O-Town's Erik-Michael Estrada, Jacob Underwood, Trevor Penick, and Dan Miller. Justin Timberlake, presumably, had better things to do.
