Princess Switch - Christmas should be about love

Stacy is the opposite of a spontaneous person, so she always has her stuff planned and organized. One day, Kevin, her best friend and the co-worker in the bakery, sign them up for a cooking competition in Belgravia. She was reluctant to go, but she does not want to stay in Chicago, so she decides to go with them. While preparing for the competition, Stacy meets Margaret, a girl who looks exactly like her. Though they just met for the first time, Margaret asks Stacy to do a favor for her. Margaret would like to switch places with Stacy for two days, because she knows that she won't be able to get out after the marriage with the prince. At the beginning, Stacy just wants to act like Margaret so that no one will find out who she is; Margaret just wants to experience her life other than being a princess. To much of their surprises, these two days completely change both of their lives.

Love is a mystery. You never know what will happen next. Sometimes, you may meet someone by luck and fall in love in a few days even when you are not actively looking for love.
