Jean Harrington is a beautiful con artist. Along with her equally larcenous father, "Colonel" Harrington and his partner Gerald, she is out to fleece rich, naive Charles Pike, the heir to the Pike Ale fortune. Pike is a woman-shy snake expert just returning from a year-long expedition up the Amazon.
But even the best laid plans can go astray. First, Jean falls hard for Pike and shields him from her card sharp father. Then, when Pike's suspicious minder/valet Muggsy discovers the truth about her and her father, Pike dumps her. Furious at being scorned, she re-enters his life masquerading as the posh "Lady Eve Sidwich", niece of Sir Alfred McGlennan Keith, another con man who's been swindling the rich folk of Connecticut. Jean is determined to torment Pike mercilessly – as she explains, "I've got some unfinished business with him — I need him like the axe needs the turkey" – and it doesn't hurt that Pike's wealthy businessman father is impressed by English nobility and eager to promote a marriage between his son and her ladyship. Soon her hapless victim is so confused and bothered he doesn't know which way is up, but, in the end, after all the twists and turns, deceptions and lies, true love wins out.
