There Is Something in the Air

The urn supposedly containing the remains of Alice's grandfather falls out of the window and breaks. To Alice's great surprise, the urn is empty and the girl learns that the grandfather didn't die but disappeared under mysterious circumstances on the 2nd September 1946 in the town of Telč. Her grandmother claims that a mysterious young man with dark glasses was implicated in her husband disappearance. Alice is determined to solve the mystery. Grandmother's story leads Alice to a shoemaker who hands her Professor Jeník's – her grandfather's – invention, called the Force-fields Accelerator. Alice tells her boyfriend Petr about the device and the young man creates a time machine following the professor's instructions. The young couple then travel back to 1946 and there they indeed meet Alice's grandfather, and his daughter Blanka, who will later be Alice's mother. Jeník is a teacher at a grammar school and a talented scientist, but he has no way of testing his theories. Petr reveals himself to the professor and shows him the time machine designed in accord with his theories. Alice persuades her grandfather to join them on their journey back to the present. The family is flabbergasted by grandfather's presence. He hasn't aged at all, and grandmother finds it particularly difficult to bear the fact that she looks so old next to him. She therefore tries to get him to return with her to meet their daughter back in 1946. The professor explains that this is probably impossible and leaves. He gets into the old pre-war Aero car – the time machine. From the window his granddaughter Alice calls after him to stay with them.
