A ship sinks in the Mediterranean, and the only survivors are a man, a dog, and a pig. The unlikely trio wash up on the shore of a small desert island and settle in to their new lives as best they can. As days turn into weeks, the man becomes ever more grateful for the company of the two faithful animals - probably all that has prevented him from going insane. As weeks become months, his attachment takes on unhealthy overtones. Loneliness gnaws away at him constantly, and try as he might to resist, the pig begins to look increasingly attractive to him.
Finally he can resist no longer and tries to get romantic - but the dog immediately gets between them, barking, snapping and growling, and the man's frustration goes on. The pattern is the same for weeks - every time the man tries to get intimate with the pig, the jealous dog puts a stop to it. The man is in a constant bad mood, and life on the island becomes tense.
Then one day they see a ship sink some way out to sea. The man dives into the water, swims out and manages to rescue a young woman. By the time she stands dripping on the beach the man is able to get a proper look at her, and is bowled over by her beauty. Her sodden clothes are little better than rags, and cling to every curve and swell of her gorgeous body. The girl is beside herself with gratitude, and begs him, with shining ruby lips, to tell her if there is anything - anything - she can do for the man who saved her life.
As he looks into her adorable doe-like eyes, blinking at him through long dark lashes, the man thinks for just a minute, and says, 'Well... can you take the dog for a walk?'
