Queen Rosalinda is taking a long weekend to visit her best friend, Carter Mason, in Louisiana. Her royal duties in Costa Luna have kept her so busy that she's looking forward to going bowling, grabbing a burger with her friend, and just hanging out at the Masons' Bait Shack. When Major Mason takes off on a mission, Rosie gets an emergency call of her own. The princess is needed at an official event. Rosie feels bad leaving Carter behind. So she comes up with a plan: turn Carter into a princess to attend the event with her.
