COUNTERFEIT LADY (1936)

Phyllis Fowler claims to be just a "simple little country girl" trying to get by in the wicked big-city, and she takes a big getting-by step when she pulls a scam that gains her a $17,000 diamond from an exclusive jewelry store. Soon, a private-detective, who has a dupe gem matching the stolen one, the police, and two gangster buddies of the jeweler are all racing each other to get the diamond back from Phyllis. The country-girl provides them all with a wild chase.
