The summer for Lolo looks good. He has just learned that he will go to camp with his cousin Joje and his friend Max. Yippee!!! He promises to bring his diary, to tell about his two weeks of camp to William who must spend the whole summer in another camp away from his friends. But, after a few days at Kamp P., Lolo will have a big surprise, in addition to making new friends ... Wow !! On the other hand, he will unfortunately also meet Victor Lamarre, aka Victor Le Mort, a dead boy drowned in the camp 50 years ago ... Certainly, he will have a long story to tell in his notebook !!
