O Delfim.

A wealthy landowner, "The Dauphin," enjoys a decadent life of hunting, drinking, and womanizing. He oversees his estate, the Laguna, with his barren wife, his one-armed manservant, and his treasured guard dog. When a sportsman (the film’s narrator) comes to the estate for his annual duck-hunting excursion, he discovers the body of the landowner’s wife floating in the lagoon and the manservant dead on his master’s bed. The Dauphin and his dog are nowhere to be found except for the mysterious barking sounds heard over the lagoon.
