High school turns into a deadly struggle for survival in the new psychological thriller Teacher's Pet. Collider has an exclusive look at the first trailer and poster for the film, which centers around a brutal battle of wills between teacher and student. The film will be released on digital and video-on-demand on February 6, 2026. In the trailer, Clara Simmons (Michelle Torian, The Demon Detective) is an aspiring young writer attending an exclusive prep school. When her beloved English teacher dies by suicide, Mr. Heller (Luke Barnett, For All Mankind) is brought in to replace him; Heller soon takes a shine to Clara, and takes her on as his teaching assistant.

She has a difficult home life, and is aspiring to earn a Yale scholarship to escape; it initially seems like Heller can help her out, but his intentions quickly prove to be far more sinister, as he develops an unhealthy fixation on his new protégé. He's a twisted psychopath with dark secrets in his past, and soon he becomes determined to destroy Clara...unless she can beat him at his own game. Who will prevail, and who will be sentenced to permanent detention?
