Dead Head.

London based petty crook Eddie Cass agrees to pick up a package and courier it across the capital. When nobody answers the door at the drop-off, Eddie opens the package and finds a woman’s severed head in a hatbox. He panics and dumps it in the River Thames. Returning home, Cass is kidnapped by the mysterious Eldridge and his heavies who inform Eddie that he has been framed for the murder.
