After Prom is an event held immediately following the Howard High School Junior/Senior Prom each year. We invite all Juniors and Seniors at Howard High, and their Prom guests, to attend a Lock-in party at the Hoyt's West Nursery Cinema 14 in Linthicum - an all-night event where students enjoy various activities, first-run movies, games, raffles for great prizes and some of their favorite foods - and, most importantly, be safe in a parent chaperoned, drug- and alcohol-free environment.
