Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn't so smart either. But now is not the time for regrets because you need to get away from these mutant zombies...fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how. [Directed by Artrake Studio, narrated by Addison Anderson, music by WORKPLAYWORK and Cem Misirlioglu].
