Sharon is a beautiful young advertising executive who is perpetually unlucky in relationships. The only male she can trust and confide in is her loyal 4-year old Golden Retriever, Ah Man. It dislikes all the men Sharon dates, except Albert, a kind-hearted veterinarian. During an accident, Ah Man and an uncouth technician Fai were zapped by lightning and had their souls swapped. Even worse, Ah Man falls in love with Sharon.
