Event planner Dina Manzo and her prom committee have the challenge of throwing a prom party, for adults only! Jim and Antonella O'Day want to throw a nostalgic prom themed party at their home in New Jersey that incorporates their European wedding anniversary trip. Dina creates a memorable prom with extravagant balloon arches, sparkly back-drops, a European outdoor cafe, high school gym dance floor, and the classic photo op area.
