Chuck Spillers, a struggling young inmate, forms a bond with Martin Brueck, an older man who visits the prison and owns a pet shop. Once Chuck is released, he eagerly accepts a job at the store, where Martin shows him his unusual collection of large cats housed in cages and explains his experiments with controlling them using electrical force fields and bells. However, Chuck's urgent financial troubles soon lead him into perilous situations that threaten his newfound opportunity.
