Senya, the creator of the Lusya smart column, experiments with algorithms, discussing personal topics, family, people around with Lusya, and tries to make her as human as possible. Lusya quickly becomes something much more than just a column - she turns out to be the only one to whom Senya can entrust her experiences, problems and thoughts. Only she knows about all the problems that Senya's daughters faced at school, and only with her does he share his feelings about relations with his wife. A smart column helps a man survive public humiliation in front of the whole family, find the son of a deputy who arranged this humiliation, and cope with the consequences of an irreparable act that Senya committed.
