Rift #4 (Of 4)

"Mary Ann, Elijah, and Cole flee the wreckage of San Francisco and head for rural Washington to find Cole's son but the group is pulled back into the web of Section 47 when a Rift opens nearby, sending an unassuming algebra teacher from the 1980s into the present. When Mary Ann learns that the teacher came through while searching for his own missing daughter, she and Cole set out to investigate the connection between the missing girls, the notorious Black River serial killer, and the spiritual nature of these Rifts in time."
