Balsa (10) and Petar (10) are best friends and cousins coming from different classes. Their mothers - Jelena (40) and Nina (45) are estranged sisters. Fortress of San Giovanni, which soars over their hometown of Kotor, is their shelter where they film YouTube videos. Petar is getting baptized in two days and Balsa still hasn't responded to the invitation. Turns out that Balsa's mother, Jelena, has doubts that Petar's father Dejan (50) is a member of a criminal organization. She uses Covid-19 virus as an excuse not to go to the baptism. Balsa's father Vlado (40) doesn't believe those rumors. During the kids' water polo training, Vlado, in order to impress Petar's parents, accepts the invitation. In the evening, Balsa and Petar act out the ritual for Petar's YouTube channel. Next day, after the baptism in church, Balsa and Petar joke around that Petar will not go to hell, unaware that the following events will send them into a hell of their own.
