While going to the local bank to get a carrot from his safety deposit box, Bugs Bunny finds himself a prime suspect when a 'tall, dark stranger' robs the bank, and Bugs is caught by FBI/CIA agent Elmer Fudd trying to leave the bank. Even though he is not wearing the attire of the tall, dark stranger, and has none of the money stolen from the bank, Bugs is still convicted and sentenced to Sing-Song Prison, under the supervision of Sam Schultz (aka Yosemite Sam).
Bugs manages to escape, and Elmer pursues him across the country, before finally hiring Sam to catch Bugs. However, Sam fails, and Elmer catches up to bugs on Mt Rushmore. Bugs dangles for his life from the edifice, but is rescued by the tall, dark stranger! Finally cornering him, Elmer and Bugs demand to know the stranger's identity. Upon removing his hat, the stranger is revealed to be Porky Pig, who claims that the motive for his disguise was that 'he had to get the picture started somehow.'
In the end, Bugs is cleared and Porky ends up in jail for his crimes.
