Muskrat family Serafin, Melania and their children are spending the winter in Wicker Bay with their rat Archibald. One of the first winter nights is just approaching. Snow is falling and the world takes on fairy-tale colors and shapes. Archibald decides to pay his neighbors a visit. In a warm, cozy burrow, he recalls past adventures and events from his lush life. He begins to spin a tale from his time living in the city. He talks about his rat friend Hubert and working together with him in a large supermarket. The rats undertook a great and responsible mission. Hubert and Archibald, at night, when the store was deserted by the crowds of customers and the staff employed there, would go out to the big sales floor and sample the goods sold there. They did this for the sake of consumers, so as not to expose them to the consequences of buying expired products.
