Grandmother's Mushroom Soup (2008)

At a free meal service organized by the Organization of the Unemployed, they are serving grandma's mushroom-based soup with an extra ingredient. Contaminated mushroom soup causes its unsuspecting consumers to become intoxicated with a virus that turns its carrier into a zombie. Justin, who barely manages to avoid the soup, escapes and joins a handful of survivors.
