The year is 2000. Thirteen-year-old Igor lives with his mum, his stepdad and Lida, a dog who has returned from space – a gift to the boy from his father, a cosmonaut. On the night Igor runs away from home, with the dog’s help he meets his 40-year-old self from the future. The adult Igor tells him that in three days’ time his father will be killed in a rocket explosion at launch, and this will ruin his whole life. Igor, his adult self and the dog Lida set off for Baikonur to stop the launch, save his father and change the boy’s future.
