Хоминг - инстинкт возвращения

剧情：

Every summer, herds of salmon return to Sakhalin Island from the ocean. Every year their number is dramatically reduced. Vanya's family is destroyed like an ecosystem of wild salmon: his parents do not live together. Yielding to the persuasion of his elder brother, his father takes Vanya with him on a journey around the island. He promises Vanya to show him spawning salmon.
