To Martinus's horror, his embarrassing blood-phobia becomes the talk of the town. Plumber de Groot even mounts a fake gushing wound crisis to make fun of doc in the pub. The local radio even feeds a generally spreading fear that his medical performances wold be dangerously hindered. When teacher Lisa calls him to examine junior genius Bas van Deurse, who fainted after a gym fall but is suspected of malingering, their unsolicited layman opinions infuriate Martinus, who refers them to hospital, where nothing serious is diagnosed. At night, Bas has a grave crisis, which the repentant MD now recognizes as life-threatening spleen crisis. The helicopter is too far and the ambulance late, so improvised emergency is the bright knave's only hope. In hospital, the source of the rumor becomes clear.
De dorpelingen leren de reden van Martinus' vertrek uit Amsterdam en besluiten hem voor de gek te houden. Martinus moet zijn angst overwinnen wanneer hij de enige is die een ernstig ziek kind kan redden voor het te laat is.
