Case File #898750 As the third season begins, physicist Peter Axon is the only remaining member of the Office of Scientific Investigation and Research team. Dr. Anton Hendricks is apparently dead, having disappeared into a mysterious apportation device known as the Arch, case manager Matt Praeger has tendered his resignation after differences with the O.S.I.R.'s Director of Operations Frank Elsinger and senior data analyst Lindsay Donner has left the team after running afoul of Praeger and revealing confidential information. Axon and Curtis Rollins, the case manager assigned to the Arch case, take their investigation to a remote area of northern Quebec after an RCMP officer finds a woman wandering alone in the sub-tundra. It turns out the woman had vanished into the Arch and then re-appeared 2,000 miles away. Lindsay Donner and Matt Praeger rejoin the team to recover Hendricks from the Arch.
