There is a ship travelling to a planet for a reason I do not remember. On their voyage, one man (let's call him Bill) is woken up a couple of years early. The ship was only stocked with food to last all of them a couple months. Bill does his best to ration the food but after sometime, he runs out. He still has a long time to go before they reach their destination. He becomes so hungry that he resorts to eating one of the sleeping crewmates. As he opens their pod, they wake up and they struggle for their lives. Bill eventually prevails and ends up killing him.
He becomes addicted to human flesh that he overeats like never before. After eating, he loses a lot of meat due to it becoming rotten. So as he continues to kill/eat his crewmates, he becomes better at the whole process. Faster forward, he basically has killed everyone on the ship as they approach their destination. When they finally land, he expects a warm greeting but is met with a flood of people that only want one thing. Him.
