13/13/13 plot
"On that day... we are demon."
Thousands of years ago, mankind decided to add an extra day to the second month of the calendar once every four years. However, age-old texts show that an extra month should have been added to the calendar every one hundred and twenty years. By only adding the days, the ancient Mayan calendar is no longer correct. Everyone is now in the thirteenth month of the thirteenth year in the new millennium. The people start spinning, turning into bloodthirsty creatures and slaughtering each other. Only the people born on February twenty-nine remain themselves. Together they will have to defend themselves and save the world from destruction.
