Orphan Black is looking to the future by diving back into the past.

A Neolution attack will cut Sarah's (Tatiana Maslany) Icelandic vacation short, and soon the clone will have to travel down memory lane to find a new ally. Beth Childs is dead, but she could hold key to the entire Leda Project mystery.

"We really wanted to look back at the first season [with season 4]," series' co-creator Graeme Manson told the Los Angeles Time. "We wanted to go back to that moment on the tracks with Beth and with Sarah. Go back and go, 'What did Sarah miss? What else happened there?'"

This won't be the first time Sarah's turned her attention to back to that moment on the tracks. Beth returned as a dream/hallucination last year, and while Maslany's long-dead character won't suddenly come back to life, there might be a lot she can learn from the season 1 character.

Check out what's in store for the first two episodes of season 4:

"After evading a Neolution attack in Iceland, Sarah returns home to track down an elusive new ally. She follows breadcrumbs and uncovers the next facet of Neolution's agenda - implanting dangerous technological devices in humans," BBC America teased. "However, those she left behind are wary about her return, not wanting to relinquish their semblance of normalcy. As Cosima struggles with Delphine's disappearance, Alison and Donnie host a pregnant and ever-hungry Helena. Meanwhile Felix, feeling like an outsider, embarks on his own journey of self-discovery."
