Ever contracted a flu before, socially distanced to avoid infecting loved ones? 

Two young brothers discover that spreading their 'flu' causes others to mutate into horrid man-eating monsters.

These bros are a global threat yet other symptoms grant them skills to slay the infected hordes. 

Morality and kinship are tested when the bros realize they aren't the only carriers of this 'bizarre flu' and their situation escalates into a grisly game!
