 A prisoner serving a 500 year stretch at Sing Song prison spends 20 years digging a tunnel under the wall. Escaping with his bag of disguises he intends to see the world but ends up instead inside the warden s television set. So, to keep from being caught, he has to use his disguises and act out programs such as a western, a boxing match and a ragtime band (but not the horse race) as the Warden keeps changing the channel.
