Every comedian knows that there's a line between sharp and cruel, that sad becomes funny at the right angle, that any moment in life, however painful or triumphant, has the potential to become a punchline. At the Chicago Stand-up School, success is about the material. But maybe Artie is too handsome to be taken seriously on stage, Olivia too scared to examine her past, and Phil too afraid to cause harm. Their teachers are obsessed with failure: Kruger trying to command his father's respect, Ashbee weary of the way his Blackness attracts a type of white admirer, Dorothy wondering how her talent is connected to her loneliness. Whether a visiting comedian - the famous, controversy-steeped Manny Reinhardt - will do more to help or to harm their cause remains to be seen.
