A jewel thief puts on a bear suit to hide out in Jellystone Park. A lawman and his bloodhound Ole Yelp pursue him. Yogi, fooled by the thief's disguise, helps him elude his pursuers. The jewel thief is caught and the credit goes to Yogi, to the chagrin of Ole Yelp who was the only one not fooled by the thief's disguise.
