Jean Harrington is a beautiful con artist. Along with her equally larcenous father, "Colonel" Harrington, and his partner Gerald, she is sailing on an ocean liner with the intention to fleece rich, naive Charles Pike, the heir to the Pike's Pale ("The Ale That Won for Yale") fortune. Charles is a woman-shy snake expert just returning from a year-long expedition up the Amazon. The young women aboard the ship compete for his attention, but Charles is more concerned with reading about snakes.
