Returning from a cricket match in Ireland, Peter Weston gains a pet alligator from another passenger who abandons it with him. He is horrified and while his first instinct is to get rid of it he develops a relationship with a young Irishwoman who appears to be entwined with the reptile. He soon discovers that Daisy is tame and seems to be the way to Moira's heart.
