Negligent journalist Zina Rykova makes a living in the “information” business - blackmail, selling compromising material and pimping. Trying to get rid of the fat she has gained, she buys a membership to a fashionable sports club. There, before her eyes, the heiress to a million-dollar fortune, Ulyana Kibildit, dies. The cause of death is more than suspicious: Ulyana, an ardent opponent of pharma, took an uncertified weight loss mixture! Who forced the girl to drink this poison and under what pretext? Personal trainer? Abandoned husband? High-ranking admirer? Or maybe one of the club members is a mysterious silent man in black? To get to the bottom of the truth, Zina will have to undergo an “innovative” weight loss program, help her ex-husband’s ex-wife get pregnant, earn a tidy sum through blackmail, get married twice and miraculously avoid death.
