The Commune is an Improvisational theatre#Improvisational comedy troupe in New York headed by Miles (Birbiglia). Other members include Jack, a talented improviser with a tendency to grandstanding; Sam, his insecure girlfriend who acts as the group's emcee; Allison, who has been working on a graphic novel for years; Lindsay, who lives off of her wealthy parents; and Bill, who loves improv but feels increasingly unsuccessful. One night, the group learns that staff from ''Weekend Live'', a ''Saturday Night Live''–style show, are attending a performance. Miles is excited for another chance to audition for the show, having auditioned and not been selected years ago. However, Jack ends up grandstanding during the performance, much to the anger of the rest of the group.
