Ivan, Amya, Konstantin, and Nikolai are a motley crew of friends living in an orphanage together. Their lives became fixated around the long and prideful life of the Onega Lake. Over innumerable days spent on the shore of the Onega, the orphans became a family. But the world had a way of disassembling them, piece by piece, until only the lake remained to shelter the last lonely boy, Ivan. This is a tale of love, friendship, and regression that delves into the lives of four friends, bound together at the center of a dream that remains their underwater sunshine.
