Ordinary young man Zhou Qizheng takes his beloved dog Dabao out for a walk, only to stumble upon a gangster's 'business' in the woods. Caught red-handed, they're both thrown into the river in a sack. In a twist of fate, their souls swap—Zhou becomes the golden retriever, and the dog becomes Zhou. Three days later, the 'dog-bodied man,' now used to standing on hind legs and scrolling Weibo with his paws, heads out with a plea for help, bumping into his crush, Xiaomei. Thinking it's just a prank, she takes 'Dabao' home, only to witness 'Zhou' naked, lifting his leg to pee at the door... The absurd comedy of swapped souls officially begins.
