The film is based on the bitter rivalry of two pigeon racers, Fred, the bell-ringer of Bruges and Neel, the fiancé of Fred's partially sighted sister. Following a major tournament, won by Neel's bird, Fred's resentment drives him to mount an attack upon his rival so ferocious that he believes he has killed him. Seized by remorse, he intends to throw himself from the belfry, but his disabled sister risks her own life to mount to the tower and try to save him.
