At a sizable public college, high-minded student Eddy is forced to room with the slovenly Stuart, but the pair strike up a surprising friendship. When attractive co-ed Alex is assigned to live with the two male students because of her gender-neutral name, a roundabout love triangle ensues. Eddy secretly yearns for Stuart, who wants Alex, but she prefers Eddy. The complex situation leads to sexual experimentation and strained relationships.
Unfortunately the movie Threesome is not yet available on Disney Plus.
