The Wagons Roll at Night

An aggressive lion named Caesar escapes from a traveling circus owned and managed by Nick Coster, but is cornered in a grocery store by clerk Matt Varney. Seeing that Matt has become an instant celebrity with the town's residents, Nick hires the farm boy to work with his current lion tamer, Hoffman the Great. Nick finds Hoffman drunk and passed out before he is to perform, so Nick convinces Matt to take Hoffman's place. When Matt does well, Nick fires Hoffman (and keeps his lions, as he owes Nick a lot of money).
