Three weeks after the nation's power grid goes down, chaos reigns. Food supplies have dried up. Fuel is running low. And the bleak, brutal winter is relentless. Fall Creek has forged a shaky peace, but the cost for safety proves higher than some are willing to pay. The town is a powder keg waiting to explode. For Hannah, home is finally within reach. But it won't be anything like she expected....

Liam and Hannah continue their dangerous journey, but their every step is dogged by a deadly adversary. Hunted and exhausted, will they have what it takes to get home? In Fall Creek, Noah struggles to protect his son and his friends. With the town running out of food and fuel and the cold as brutal as ever, they're forced to make compromises that may place them in even greater danger.

Three months after an EMP attack destroys the US power grid, starvation and disease have killed millions. With the end of winter finally in sight, the town of Fall Creek, Michigan balances on the precipice of collapse. They have suffered and sacrificed. But to forge a future worth living, they will have to face the darkness within themselves. Each must decide - will they retain their humanity or choose survival at any cost?

On the fifth year anniversary of his wife Hannah's disappearance, small-town cop Noah Sheridan takes his son Milo to a local ski resort for some much needed father-son time. In a blink, the power grid goes out. Phones and cars stop working. What starts as a day of holiday fun soon turns into a deadly fight for survival. And when an impending blizzard cuts off the town from the rest of civilization, it'll take everything Noah has to keep his family and friends alive.

In the middle of the coldest winter on record, a super EMP destroys the power grid. No electricity. No cars or phones. Worst of all, no heat. The country is plunged into instant chaos. But for 26-year-old Hannah Sheridan, it's the best day of her life. For the last five years, she's been held captive by a sadistic psychopath, until the EMP releases the lock of her prison. Hannah emerges from her underground cell into a hostile winter landscape with no way to call for help, no vehicle that will drive, armed with nothing but the clothes on her back and her own determination to survive.

In a heartbeat, everything grinds to a halt. On Christmas Eve, the lights go out. Vehicles stop working. Communications break down. Reclusive former soldier Liam Coleman doesn't want to be anywhere near bustling downtown Chicago the day before Christmas. But his twin brother and his pregnant sister-in-law need him. But mere minutes after leaving O'Hare, their car crashes, along with hundreds of other vehicles. When Liam's phone stops working, he begins to suspect something more sinister than a local power outage.

Months into the apocalypse, the zombies show no signs of dying, but it's clear everyone in Sunset Park will die without enough food to outlast the undead. Add in the less-than-sociable new neighbors only blocks away, and the hunt for sustenance has come to feel more like a race than a ramble. Sylvie is happy in her new home with the people who've become like family, though she's still working out how to let them into her heart. Eric wants in, and he wants to find his sister, but he can't do both at the same time.

Sunset Park is gone. People are missing. Sylvie, Eric, and the other survivors have crossed the water to the security of a new Safe Zone, where they hope to heal their battered hearts, amass an armory, and get back at the ones who took it all away. But with zombies on the move and few resources to speak of, it’s harder than expected to plot their revenge. For some, it’s harder still to garner their resolve, since vengeance means more of them will die. But safety is ephemeral in a city where food is short and tensions are high. It seems fate may leave them no choice but to fight.

Sylvie Rossi has the loner thing down pat, with the exception of her best friend, Grace. But when the two are trapped in a hospital during the last gasp of a dying city, alone time is no longer an option. A nurse's offer of sanctuary promises Sylvie the supplies she needs to survive the zombies - it's the coexisting with people that might do her in. Eric Forrest will do whatever it takes to get into the dead city for his sister, including ending up dead himself. He's used to taking risks, but with every mile he travels death looks likelier.

Rose Winter has enough problems. With a marriage going down the tubes and a dreaded anniversary party on the horizon, the last thing she needs is the zombie apocalypse. She wanted to get drunk and sing karaoke, not murder her undead neighbors. It’s clear the party’s over, however, now Rose has more problems - a missing husband, an overbearing houseguest, and keeping her family alive.
