The family from the 4th floor are reasonably sane people. Krists is a brash teenager who lives in his dreams more than in real world and has a keen interest in the neighbor girl Unda. Ineta, Krist's mother, is a moderately hysteical being, a primary school teacher who devotes all her awake hours to obsessively watching shows on TV. The tranquil balance of this family is disrupted one night when it turns out Krist's world of sleepwalking has began to endanger the life in awake.
