Four people disappeared without a trace on their birthday. Four people who are in no way connected with each other: a middle-aged woman in the military, a man preparing to become a father, a successful accountant - a mother of two children and a young student. The only thing they have in common is the strange cards they receive that say, “Your gift is a game. Play poorly?” The police are in no hurry to take on these cases - what does the law care about someone’s strange games? But the families of the missing are sure: everything is very, very serious. Experienced psychologist Augusta Bloom and her partner Marcus Jameson take on the investigation... and very soon come to a shocking conclusion: perhaps it is not for the four missing people that we should be afraid, but for them.
