The water police raise the alarm: A woman reports her husband missing, while a floating inflatable boat without occupants is sighted on the outer Elbe. At the same time, another boat reports that an inflatable boat is circling unmanned – a worrying report. "If he's fallen into the water, it's a matter of minutes!" warns Kai Schöps, second engineer of the "Anneliese Kramer." The sea rescuers anxiously scan the water with binoculars, while a helicopter supports the search. Time is running out.
