Daniel didn’t hear his son, Krzysiek, leave the house and head for the bridge over the Vistula, where he was last seen. A CCTV camera captured Krzysiek before he disappeared: either he jumped into the river or walked off the bridge. Since then, Daniel and his wife have been living in limbo, torn between hope and fear. Unwilling to wait for a breakthrough in the investigation, Daniel builds a boat equipped with cameras and drones to search the river himself. The search consumes him. The solitary hours spent on the boat offer him an opportunity to look back on his life.
