Playwright Adam Rapp has a pretty bleak outlook on life, and that plays out in his tale of two buddies who end up in an Amsterdam apartment and contest over a mysterious young woman who shows up on their doorstep. Red Light Winter, the next production by Untethered Theater at Clifton Performance Theatre, was considered for the Pulitzer Prize for drama in 2006, and it’s a showy work in which Rapp shows off his flair for piercing dialogue. One of the guys intellectualizes to the point of paralysis, while the other effortlessly grabs the social limelight. They’re trying to relive their twenties, but a beguiling prostitute changes the dynamic of friendship in some terrifying ways. Director Paul Morris calls it “a love story of missed opportunities.” It’s the right kind of script for this fledgling theater company. 8 p.m. Friday-Sunday. $15. Through Feb. 2. Clifton Performance Theatre, 404 Ludlow Ave., Clifton. 513-939-0599, cliftonperformancetheatre.com.
