During the cold and rainy off-season a man (Gérard Philipe) arrives in a seaside town and, giving his name only as Pierre, checks into the only hotel which remains open. His arrival arouses curiosity and a degree of suspicion, as people note that he appears to know the area, yet gives no explanation for his presence at that bleak time of year in the dead-end town. The elderly father of the hotel owner, now a mute invalid, shows signs of recognition but his condition prevents him from voicing what he observes. Pierre is treated with barely disguised petty-minded intolerance and hostility by the hotel owner, guests and habitués, but develops a friendship with Marthe (Madeleine Robinson), an all-purpose employee at the hotel. Pierre also notices a 15-year-old boy – employed as a dogsbody at the hotel, where he has been placed by the local state-run orphanage – who he has spotted engaging in rendezvous with Mme Curlier, a middle-aged female guest. His attempts to engage the somewhat surly and reticent youth however meet with rebuff.
