After an accident, Hsia Cha switched bodies with his grandson, Hsia Tse Fang. This is a story about how to do the right thing when the soul of a 59-year-old man is stuck in the body of a 17-year-old young man.

Days before his 60th birthday, Hsia Cha and his grandson Hsia Tse Fang get involved in a train accident which results in a Freaky Friday situation. To give Tse Fang his youthful body back, Hsia Cha pleads with Yeh Hai Yuan, the kid next door, to help him figure outwhere Tse Fang's soul has gone. Though it's an unbelievable situation, Hai Yuan chooses to trust the neighbor kid who insists on being called by his granddad's name. As their budding friendship grows, Hai Yuan begins relying on Cha's companionship and decides that he might feel something more than friendship. Yet, Hsia Cha suddenly senses on his fingers a red thread of fate that links him to his soulmate, leading him to believe that the body switch was not an accident, but the last opportunity for him to fulfill his side of a pact with his wife, Yu Chan.
