This is a story about child trafficking. Two young baby snatchers abducted an older boy, Dou Dou, who ran away from home to see the sea. The kidnappers tried and failed to find a buyer for the boy because of his age. Unable to make a sale, they decided to send the boy home, but not before Dou Dou discovered their identities and nefarious intentions. Concerned he might be fingered for his crime, the male kidnapper, Er Tiao, decided to kill the boy and guarantee his silence. Lucky for Dou Dou, the female kidnapper, Su Su, pitied him and she refused to let Er Tiao commit murder. Su Su insisted Er Tiao try again to sell the boy. So, Er Tiao took the boy to an organ trafficker, Ma Wu. Just as Ma Wu offered a bounty for the boy, Su Su learned the true nature of Ma Wu’s business and furiously stormed out of the meeting, taking Dou Dou with her. In the massive row that inevitably followed, Su Su feigned complicity in a plot to bury the boy alive. While Er Tiao went to dig a hole for the boy in the back of a hill, Su Su absconds with Dou Dou. Eventually, Er Tiao tracked them down using the GPS on a previously stolen phone still carried by Su Su. In the subsequent confrontation, Su Su is stabbed while protecting the boy from Er Tiao. Scared, Er Tiao took off running. On the ambulance hastily rushing Su Su to the hospital, Dou Dou saw the sea.
