Two small town criminals must get their hands on some drugs. Their search takes them to the surgery of an off the wall doctor in financial difficulties. What was meant to be a simple robbery becomes a complicated affair and the crooks find themselves barricaded in the doctor’s office with a number of his wacky patients as hostages, including a simple minded farming couple who mysteriously cannot get pregnant; and an eccentric hypochondriac who develops an affection for her captors.
