Exception to the Rule is set in Room 111, the classroom where an inner-city high school hosts detention. One day, five detention regulars are surprised by the addition of a sixth: Erika, the best student in the school. Written by Dave Harris, who is also a poet, the play sees the students flirting, fighting, smoking, and trying to escape their punishment. Roundabout Theatre hosts the world premiere, which features a cast of newcomers. —Jensen Davis
