According to producers, "If/Then is a contemporary new musical that follows two distinct storylines in the life of Elizabeth, a city planner who moves back to New York to restart her life in this city of infinite possibilities. When her carefully designed plans collide with the whims of fate, Elizabeth's life splits into two parallel paths. If/Then follows both stories simultaneously as this modern woman faces the intersection of choice and chance."
