A nurse in the dispensary of an English hospital is suffering with a migraine, and accidentally dispenses the wrong medicines to three patients.

The police and doctors have little time to locate the patients before the consequences are fatal.

However, the husband of the third uses the pills to kill his wife, who is already suffering from a terminal illness, and takes one himself to join her in death.

The Monthly Film Bulletin wrote: "This peculiar short story is an uneasy mixture of suspense, comedy and tragedy (the final mercy-killing and suicide).

Since the whole thing is rather pointless, with nothing to say on the subject of mercy-killing, it seems an unnecessary reflection on hospital authorities and discouragement to their patients to dwell on the possibility of such a serious error.
