Duangjan is a cold-thoroughbred, youthful homicide for a cabal group. One day, due to a failed charge between Duangjan and Lok — an homicide within the same group — Duangjan ends up falling off of a precipice. Still, she’s saved by the head of the public demesne, Atiruj. When she wakes up, Atiruj realises that the youthful woman he saved has developed amnesia. The formerly cold and advised killer suddenly turns into a cheerful little girl and finds herself not only with a new name”Chao Chao”, but also a fake hubby, Atiruj — who just so happens to be escaping his mama who was determined to get her son married.
