Фильм повествует об отношениях существа-амфибии и девушки по имени Элайза на фоне противостояния США и СССР во времена Холодной войны. Скучная и одинокая жизнь Элайзы получает необычный поворот, когда она и коллега Зельда внезапно обнаруживают результаты эксперимента.

An old lighthouse keeper who lives with his daughter secretly keeps a prehistoric fish-man by feeding it scraps and fish. One day he misses the feeding and all hell breaks loose.

One decent citizen was having lunch and indifferently looking at the fish in his aquarium. But suddenly a real monster emerged from the muddy water. However, unwillingness to strain even to save his own life led the hero to slavery. Or maybe nothing has really changed in his life?

A pair of filmmakers and monster-hunters embark on a mission to capture and film a creature residing in a lake.
