An adventurous story about traveling through time and friendship across history. One summer morning, siblings Klára and David find a frightened little boy in front of their parents' cottage. They would like to leave the care of the strangely behaving child to someone more mature, but they are alone, so they have no choice but to take little Artur under their wing and try to return him to the place from which he wandered off. That same morning, another unusual visitor arrives at Dr. Hávová's veterinary clinic. A man whose behavior is somewhat unusual for today's world. He calls himself Robert and tries to pay for the food he has been given with gold coins. Independently of each other, the protagonists of the story uncover clues that lead to the cottage of a local eccentric named Kobza and further to a cave called Devil's Mouth. Is this cave really a gateway to another world and time? And will Artur and Robert manage to get back home through it?

Autumn 1988. Renata is studying journalism. She lives with her jealous boyfriend Standa, whom she occasionally cheats on. She edits the school magazine and is perhaps a little more daring than the others, mainly because she doesn't want to be the daughter of her father, a bigwig at the Ministry of the Interior. But the situation is getting out of her hands—Renata's anti-regime mini-activities and her romance with dissident Holý are getting the attention of the STB. Her dad is worried about his career and maybe even convinced that he should disinherit her. Her relationship with Standa is getting complicated.

Two families, Sebkovi and Krausovi, are celebrating Christmas, but not everyone is in a good mood. The teenage kids think that their fathers are totally stupid, and the fathers are sure that their children are nothing more than rebels, hating anything they say.
