How Long Is “The Body Snatcher”?

In 18th-century London, a brilliant surgeon refines his technique on cadavers supplied by a grave-robbing coachman. When the cab driver and graverobber John Gray threatens to reveal the surgeon's secret if he does not operate on a paraplegic girl, the surgeon requests another human specimen for practice. However, he becomes suspicious when Gray returns with the body of a girl whom he saw alive only hours before.
