Edgar M. and his mother come abroad a small ship to Eden Sanatorium spa. It is here that the wife, wronged by her husband, will seek a cure for her bad headache, while the 13-year-old Edgar M. is fighting his first male impulses as well as 'enoresis nocturna', the prettier word for wetting one's bed. The boy's amazed gaze hungrily devours the diverse hotel guests, their love joys and sorrows, while passion lustfully penetrates the walls, carried by the voice of the enchanting opera singer.
