"Why do they have to find out that they have a child?" Hela asked. "I don't know," said Daniel. "As far as I know, Guy does indeed exist," said Hela, "and his parents are locking him up in the house and not allowing him to go out..." These two things make Gali and the friends on the edge of his seat. The first - what is really going on there in the home of the new kid, the new kid in the kibbutz? And the second - will their team be able to save its honor in the upcoming football tournament? When Gali discovers the big secret of Hadhadus, she has to decide whether to keep his beliefs or reveal his painful secret in front of her childhood friends. Who will she choose?
