In the year 2023 the U.S government started to work on a drug that was capable of taking any body and increase its muscles size and strength, the first test on an actual human was performed on the year 2025, the results were horrendous, the human dramatically gained muscle size but the tested subject became extremely dumb and violent, he was described as a gorilla and had to be killed right away. The drug stopped being produced and tested. In the year 2028 a hospital in Michigan reported a huge number of people infected with an unknown virus, the virus got the name of "gorilla virus", people infected by it were described as wild animals that just wanted to destroy things, including other humans. The virus rapidly spread across the U.S and later across the world.
The trailer is a little more interesting:
