A couple of rich girls at a private boarding school find themselves mixed up in gambling and blackmail, and must steal from their parents to pay their gambling debts.

While trailing the school French teacher, Professor Bedoin, hoping to catch him in a romantic interlude, Lillian Harding and Katherine Thompson, students at the exclusive Lakeside School for Girls, follow him to Angel's Roost, a gambling joint and learn that he is a regular player there. Chance Landon, the manager and henchman of a mysterious and unseen owner, induces the girls to play on credit. Lillian, the younger of the two, falls in love with Chance, and over a period of days, writes him several passionate love letters. When the girls have lost several thousand dollars at the crooked roulette wheels, Chance uses the letters as a club to make the girls steal valuable family jewels to make good their losses. The thefts bring insurance investigator Jimmy Parker to the school posing as a gym instructor. He stumbles upon a clue which makes Katherine confess her part in the crimes, and with this to work on, he sets out to trap the club's ring leader.—Les Adams <[email protected]>
