Oleg was a brilliant programmer. Immersed in the virtual world, he forgot about everything. Once, having picked up a laptop forgotten in a minibus, Oleg found in it an interesting spy program and some chemical formulas, but did not have time to study them properly, feeling bad. It would seem a banal flu, but Oleg got worse and worse, and his friend Gena brought a familiar girl-doctor. Natasha, realizing that the situation was very serious, sent Oleg to the hospital, where it turned out incredible - he was struck by an artificially modified Spanish flu virus.
