Zombie apocalypse

A few years ago, everything was peacefully, just a normal world. But in 2019, a scientist created a zombie, but he didn't know how the zombie would react. At night, he left the zombie in a cage, and the zombie, somehow breaks the cage, and as it walks around the laborator, it bumps into a potion where it turns it into a mutant zombie. The next day, when the scientist comes to the laborator, sees the cage broken and the laborator a total disaster. Suddenly, the mutant zombie appears. None knows what happened with the scientist. Some are saying he turned into a zombie, some are saying that he escaped and ran away, some are saying that he's waiting there, in the dark, waiting for the right moment to create more experiments. The mutant zombie disappears in the woods. In 2020, the zombie appears again and starts infecting the people.
