Ma Chao, a 28-year-old single office drone, discovers that every time he climaxes, his soul randomly jumps into the body of a nearby creature that is also climaxing. From his female coworker Xiaolin, a female dog, his buddy's girlfriend, to the gluttonous Liangzi, each jump is more mortifying and perverse than the last. He enjoys it and falls apart at the same time, swearing off lust one moment and unable to resist one more round the next.
