Pups (1999)

"What happens when a kid finds a gun or a gun finds a kid?"

When troubled teen boy Stevie (Cameron Van Hoy) and his girlfriend, Rocky (Mischa Barton), attempt to rob a bank without any forethought, the situation rapidly deteriorates. Soon the young couple is holding bank customers and employees hostage, while law enforcement gathers outside. Daniel Bender (Burt Reynolds), a veteran negotiator for the FBI, is charged with assessing the crime scene and ending the standoff as quickly as possible, but Stevie's short fuse considerably complicates matters.
