Where The Tracks End

They each remember one thing: They were at Isaac's party.
But when they wake up, they aren't at the Stoneson house.
May, Sergei, Maeve, Jamie, Alice, Beth, Ross, and Ivy...
All woke up on a moving train.
How did they get there?
Where is the train going?
All of these questions buzzed around the main cabin until everything went black.
Something broke the tracks...

It's a game of survival.
