Tom Pinfold, a mourning widower, murders a haematologist and tries to commit suicide. After being incorrectly pronounced dead by paramedics, he wakes up on Harrow's autopsy table. Harrow tries to assist the badly injured man, but Pinfold turns on Harrow and threatens him with a knife, holding him captive in the exam room. It's a public holiday and they're alone in the morgue, so Harrow can't call for help and must use his wits to take control of the situation.
