Reality Show Murder Case

One early morning, the body of a boy was found on the beach in the small town of Crescent Bay. It was the youngest child participating in the filming of the reality show, 12-year-old Jason. . From the first day of reality show filming, this crew has been shrouded in lies. Four families crush each other around greed, fame, wealth and love. When the director discovered that the other three children were ostracizing Jason, he cut out a promotional video "out of context" and involved the fathers who had not participated in the reality show; the fathers came to visit the class, and the conflicts among the four families became more and more intense. The lies of each family were on the verge of being completely exposed. Some people ran away for love, some committed evil because of greed, and some wanted to be "silenced" for fame and fortune... On the night Jason was killed, three nanny vans passed by the crime scene. So, who killed him?
