Dmitry is a lonely, aging man having a recurring nightmare. He randomly comes across a clinic that helps treat insomnia and bad dreams. The doctor at the clinic provides Dmitriy with a device that replaces his bad dreams with wonderfully vivid pleasant ones. On his first night with the device he unlocks a forgotten romance between his younger self and a gorgeous woman named Masha. These new dreams inspire Dmitriy to reunite with his old friend and take up playing his dusty guitar again. However, as he experiences the ups and eventual downs of his relationship with Masha, he begins to understand how reliving these memories and being doomed to wake up from them might become a nightmare in itself.
