While enjoying a solo fishing expedition, Dr. Paul Martin (Griffith Jones) is captured by a lonely and beautiful mermaid named Miranda (Glynis Johns). She agrees to release him if he will show her the city of London for one month. Dr. Martin convinces his wife, Clare (Googie Withers), that the woman he has brought home in a wheelchair is an invalid patient, but it isn't long before Miranda's strange habits and powers draw the amorous attentions of Dr. Martin's male friends.
