It’s a seemingly normal Tuesday at school when, out of nowhere, a giant tear forms in the sky. Out of the tear falls doppelgangers of some students, with some minor changes to their lives as their ‘what ifs’ are answered. The students must work together in order to return the doppelgangers to their alternate universe, before they become too sick. A human chain supports the young people to fix the tear and send their doppelgangers home again.
