They're all rich and Phuree is the heir of P. Paul's shoe brand. Phuree wants to show that Prim and her buddies are deceivers, so the guys also lie about who they really are to get closer to the girls and lure them into confessing. But after spending so much time together, Phuree and Prim fall in love. How can things work out between them, though, when the foundation of their love is a lie?
