Unbeknownst to two teenagers—Ralph worried about a history exam he didn't study for and Sarah having studied all weekend—a flu pandemic with apocalyptic proportions rages over the world. On Monday, they arrive at their high school besieged by men in hazmat suits, escorting infected teenagers to buses. Ralph is forced on one of these quarantine buses and Sarah, along with the remaining healthy student body, gets quarantined at school.
This flu however is worse than the 1918 Spanish Flu that killed a hundred million people—much worse. This flu turns its victims into the walking dead. The few not infected are left not only with the grief of their family and friends passing, but also with the horror of their families, friends, and neighbors trying to rip the flesh off them.
Ralph—unsure about the real destination of the bus and trapped inside with kids that are getting worse by the minute—may not get to the destination in time before the first one dies. Sarah, trapped at school, deals with a worsening situation that she soon needs to escape from.
Will the zombies feast on their young flesh or will they escape?
