Fluffy the lion is the main attraction in this comedy. He is the subject of an ambitious experiment done by Daniel Potter (TONY RANDALL), a scientist trying to prove that even a wild animal like a lion can be made into a pet with proper training. Wherever he goes, Potter's ponderous pet incites mayhem among the region's fearful residents. To escape his panicky neighbors, Potter and Fluffy hide out in a hotel, where, the owner's daughter (SHIRLEY JONES) falls for the unlikely duo while everyone else freezes or collapses in a panic. Our heroes find themselves on the run from the law when Fluffy is accused of eating someone. Can Potter stop the police before they shoot an innocent lion?
