A complicated puzzle emerges in the new "State Like Sleep" trailer.

Released Wednesday, Nov. 28, the preview introduces Katherine Grand (Katherine Waterston), a widow whose actor husband (Michiel Huisman) died unexpectedly by suicide the year before. When she gets a phone call that prompts her to search for answers, her trail leads her to a gentleman's club and its owner (Luke Evans).

The trailer only shows us some of the many puzzle pieces, of course. How they fit together is an even bigger question, but it looks like it'll be fascinating to get answers. Watch the trailer below.

The drama is directed by Meredith Danluck, who also wrote the screenplay. Her cast includes Waterston, Huisman, and Evans, plus Mary Kay Place, Michael Shannon, Mark O'Brien, Bo Martyn, and Ian Matthews.

"State Like Sleep" had its world premiere in April at the 2018 Tribeca Film Festival, and it opens in theaters on Jan. 4. The film also hits on demand on Jan. 1.
