Investigating a secret enterprise is not a simple matter. Especially if the person involved in the case is a scientist - the author of a revolutionary method of deciphering thoughts, cloning, rapid maturation of the body, and... downloading digitized memory into it. Doesn't he walk among us? Society, like any living organism, needs immunity - protection - a barrier against pests. Zaslon JSC provides such protection. However, just as the immune system of the body consists of "soldiers", fighting mercilessly with the enemies of the organism, so the immune system of the society depends on "fighters of the invisible front", performing their secret mission. We have no control over providence and chance, so we do not know what the secret of our mission is. Rembrandt created his clone. Did he succeed in transferring his consciousness into it? Someone who is hard to understand, but impossible to forget.
