Yosemite Sam robs the Last National Bank and makes his getaway in an airplane flown by Bugs Bunny. Sam falls out of the plane and dies. Sam ends up in Hell, where he makes a deal with the Devil. If Sam brings Bugs to Hell, he will be set free, but if he fails, he will remain in Hell forever. Sam gladly accepts the deal and the Head Devil sends him back to the world of the living.
After three failed attempts on Bugs' life, the Devil decide to give Sam "one more chance". However, Sam has had enough and tells the Devil that if he wants Bugs, he can get him himself and announces that he is staying in Hell while wearing a devil suit and wielding a pitchfork.
