Have a Nice Rest

Plot: A technological race of emotionless aliens arrives on Earth. For the mission to find a source of energy and save their kind, the best representatives of the male and female sexes, Alpha 1 and Alpha 2, were chosen, and for the most successful contact with people, the wayward "human scientist" Beta set off with them. Thanks to their gadget bracelets, all three take on human form and receive the names Alexander, Igor and Larisa.
