Welcome or No Trespassing: In the Young Pioneer camp the director is afraid of harmful accidents with children and his subsequent responsibility for them. Accidents in his view appear, when formal rules are violated. Hence, he believes, that all should be done according to formal instructions and regulations. One boy named Kostya Inochkin (Viktor Kosykh) trespasses the rules, swimming to island. He is expelled from camp, but fearing to bring sorrow to his grandmother, returns to camp illegally. Soon other kids start helping him to stay, being more smart than adults. Adults are added to the plot later and also oppose to directors formalism. Finally the director is removed and expelled to town.
