Dead Burger (2017)

Sometimes, you should just listen to the customer. Like in this case. A voodoo priest walks into a small town diner and orders a burger. He requests no tomatoes due to an allergy. When he receives a burger with tomatoes, he is enraged and sure of their intent to end his life. In return he raises the dead, and a group of young people who were up to no good in the cemetery are the only witnesses. They fight through the zombie hordes to get to the gun store, where the owner Jim and his brother Burt join the fight for the town's survival.
