A dog, a sheep, and Justin Bieber are shipwrecked and wash up on a deserted island. Luckily they find food and shelter and are soon settled into a livable routine.
The highlight of their routine happens every evening. They sit together on the beach and watch the sunset before going to sleep.
After about a month with no human contact, Justin begins to feel very lonely. One evening on the beach, while watching a particularly stunning sunset, he finds himself quite heartsick and lost in romantic memories.
As this is happening, it occurs to Justin that he may be stuck on the island idefinately, and being a boy with "needs," he finds himself suddenly and powerfully attracted to the sheep.
At the exact moment he looks at the sheep, the dog sees what is happening, gets jealous, growls at Justin, and that is the end of that.
Several weeks later, a beautiful teenage girl washes up onshore, badly hurt. Justin nurses her back to health for the next month, and they develop an extremely deep emotional bond. The first night that the girl is able, she joins the three out on the beach to watch the sunset.
Justin, being a normal boy, soon feels his passion rising up through his loins, and he decides to act on his impulses. He leans over to the girl with a sly smile on his lips and says, "Uh, do you mind taking the dog for a walk?"
