Bugs is looking for a "sanctuary" as hunters are firing all around him. He digs a deep hole and comes out in the yard of "Sing Song" prison, where a guard immediately captures him. That guard - Sam Schultz - is really Yosemite Sam, as we know him, with a prison guard's uniform.

Sam puts the stripes on Bugs and has him pounding rocks. (All the old prison movie clichés are used in this cartoon.)

The rest of the animated short has Bugs trying to escape from the prison, getting caught all the time, and constantly outwitting the dumb "Sam Schultz" with every ploy....at least temporarily. The humor is decent, about average, but very watchable.
