Disclaimer: This was written before everything with Coronavirus happened, and it is an original story, so I have the rights to the characters, plot, and everything else.

This takes place in the United States of America, where a series of terrorist attacks hit throughout the country. At some point during the attacks, a toxic gas is released which kills you upon inhalation. The story surrounds 4 girls who are at school when the attack happens and are forced to, ironically, quarantine together in a classroom (again this was written b4 COVID and all that-this is just a coincidence).
