Wormwood, the six-part series produced by Moxie and directed by Errol Morris, got a thrilling trailer this week ahead of its December 15th Netflix release.

The series explores the CIA’s LSD experiments in the 1950s and their deathly impact on one family. It blends interviews, enactments, and historical elements as it tells the story of Frank Olson, who’s death sparked interest and concern over the government’s experimental methods.

The documentary has received rave reviews since its premiere at Telluride Film Festival. Morris is known for his tremendous documentary work, with The B-Side seeing a lot of success earlier this year.

Be sure to watch Wormwood on Netflix on December 15.
