Leon

Plot:

Sam discovers that demons don't work on Halloween. Unfortunately, the depressed Devil decides to make Sam's assignment even harder to cheer himself up. Sam and Sock capture one soul, that of Leon Czolgosz, an escapee who assassinated President William McKinley back in 1901. But before Sam can return him, Leon tries to convince them that he's changed. The Devil then sends Sam to recapture a second soul, a serial killer who plans on starting a new murder spree.
