THERE ARE PLENTY OF FISH IN THE SEA: Ky Dickens didn’t exactly have a fun time coming out of the closet to her sorority sisters at Vanderbilt University, but the incident led to the creation of Dickens’ documentary, “Fish Out Of Water,” which explores seven Bible verse used to condemn homosexuality. The doc screens at Columbia College’s Film Row Cinema, and Dickens will be on hand for a discussion afterward. 1104 S. Wabash Ave.; South Loop. 6:30 p.m. Free.
