Daniel did not hear his son Krzysiek leaving the house and heading to the bridge over the Vistula, where he was last seen. A camera captured him — and then he disappeared: either he jumped into the river or walked off the bridge. Since then, Daniel and his wife have lived suspended between hope and fear. Unable to wait for a breakthrough in the investigation, the father builds a boat equipped with cameras and drones to search the river himself. The search consumes him. The lonely hours spent on the boat become a chance for him to reckon with his life so far.
