The everyday lives of office employees in the Scranton, Pennsylvania branch of the fictional Dunder Mifflin Paper Company.

Comedian Aisha Tyler hosts this improv comedy show where the actors on the show - Wayne Brady, Colin Mochrie, Ryan Stiles along with a special guest each episode -must put their comedic skills to the test through a series of spontaneous improv games, prompted only by random ideas supplied by the studio audience.

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.
