On a cold February morning, 12-year-old Niki and his family arrive at the Kharkiv metro station to take shelter from the terrifying war raging outside. For Niki's family, daylight is synonymous with mortal danger, and the boy is not allowed to leave the station premises, living under the constant glow of their neon lights. While aimlessly wandering around the abandoned cars and full platforms, Niki meets Vika, and a new world opens up to him. As their bond strengthens, the children find the courage once again to feel the sun on their faces.
