In this hilarious and poignant look at the life of improv impresario Del Close, we follow the comedy trailblazer from his early sideshow act to his influential and contentious rise at The Second City, mentoring such comedy legends as Bill Murray, John Candy, and Tina Fey. The film renders a lively, multi-layered picture of a man and his mission, riding on the edges of genius and despair, creativity, and insanity.
