After Mickey gets over the prison wall, he tries to run away, but is pulled back by the weight of the ball and the chain breaks, yet Mickey still carries the ball when he could just run away and leave the ball.
In this black and white short, Mickey Mouse is in prison. God only knows what on earth Mickey Mouse could've done to deserve this. The first half is a musical sequence with the prisoners dancing around the prison yard. The rest of the short deals with an escape attempt by Mickey. All around, it's only mildly amusing.
