Former classmates Alexandra (Stephy Tang) and Alexis (Kary Ng) may share the same name, but they couldn’t be more different. Alexandra is beautiful, intelligent, rich, and completely insufferable. Self-centered and patronizing, she’s an expert in quick put-downs, nasty name-calling, and brokering gossip into profit. Alexis is a simple-minded, pure-hearted, and hard-working gal who is constantly bullied by her future sister-in-law’s family with whom she stays. Crossing paths again by chance, the two girls don’t want anything to do with each other – until a freak accident causes them to switch bodies!
