Fear the Walking Dead
Travis (Cliff Curtis) will have to learn how to survive in the Season 1 finale of "Fear the Walking Dead." AMC

Everything is about to change on “Fear the Walking Dead.” AMC’s new companion series has primarily focused on the events following the zombie virus outbreak. From the electricity going out, to a military takeover, those locked behind the gates have been shielded from the horror that lurks in the streets. But it sounds as if the Los Angeles survivors will be in for a rude awakening in the Season 1 finale.

When episode 5 ended, the group learned about “Cobalt” -- the code name for the evacuation of the military and the “humane termination” of those at the hospital. The synopsis for episode 6, the finale, teases that Travis (Cliff Curtis) and Madison (Kim Dickens) must find “new ways to protect their families.” But how will they do that when they don’t know what lies ahead?

A new video posted by the “Fear the Walking Dead” official Twitter account reveals some of the problems that the main characters will face in the finale.

For starters, Nick (Frank Dillane) is stuck in the military hospital facility. However, he may have lucked out thanks to his mysterious cellmate, Strand (Coleman Domingo). Right now, the only thing that viewers know about Strand is that he’s wealthy and has a plan to escape. The exact plan is unclear, but it involves Nick.

“Everything has to fall into place for his plan to succeed,” executive producer Gale Anne Hurd teases in the video. “And ultimately Nick becomes a very important part of this plan.”

It sounds as if Nick will be adapting to survive. But can the same be said about Travis? Despite everything happening around him, Travis is set on doing things humanely. Meanwhile, Madison and Daniel (Rubén Blades) have already shown that they’re willing to do anything to protect their family and survive -- like torture Andrew (Shawn Hatosy). However, Travis’ decision to maintain his moral compass will become increasingly difficult -- especially since his family is about to be abandoned by the military.

“The big hit for the end of that episode is we’re going to have to take care of ourselves now because the National Guard is about to leave,” executive producer Dave Erickson explained of the future of the survivors. “And when they leave we won’t have anybody bringing us food. We won’t have anybody trying to get the electricity up and running. We’re going to have to learn how to survive.”

And unfortunately surviving means dealing with a sports arena full of zombies.

Watch the “Fear the Walking Dead” Season 1 finale when it airs on AMC on Sunday, Oct. 4, at 9 p.m. ET.
