A man dies of a heart attack whilst flying his plane, but the town medical examiner, a charmingly eccentric Cuban doctor, is convinced that there was foul play. By chance Ironside and Ed are on their way to visit and soon become involved in his investigations; but between pregnant ducks and volatile banana cocktails they have their work cut out as never before.

When Ed returns from a holiday he finds the Chief missing, and a series of obscure clues pointing to the suggestion that he has been kidnapped. In truth Ironside has been waylaid by an old enemy, a mobster seeking his help to solve a murder, but a gang war is brewing and the Chief needs his team to find him in time to stop it erupting unchecked.
