Riff Raff shows his newly formed gang the tactics of guerilla warfare. Sweet Polly Purebred goes to the museum where Underdog is standing by guarding the Whistler's Father painting. Meanwhile, outside, Riff and the gang are disguised as horses to carry out the first guerilla warfare tactic 'Hit and Run'. As the horses stampede the museum they steal the painting. But Underdog gives chase and catches them at the Finish Line he sets up.
