[3] A young couple Clive and Jean Croft are spending part on their honeymoon on a remote Scottish island.

Their enjoyment of the picturesque retreat is soon interrupted by a series of encounters with the other visitors to the island, gun-toting security for an egotistical professor apparently attempting the age-old practice of alchemy to create gold.

The arrival of an equally well-armed gang intent on stealing the gold puts the young couple in extreme danger.
