Moscow. 2020 year. The media warn that soon a dangerous meteorite will sweep near the Earth with great speed. But the wealthy restaurateur Vadim does not care, so he does not change his plans and is in a hurry to celebrate the purchase of a new establishment. On the way to the restaurant, Vadim calls his friend Nina to invite her to a banquet. But due to a time anomaly associated with a meteorite, another Nina, a thirteen-year-old girl who is dying of hunger in cold Moscow in 1942, picks up the phone at the other end.
