When an earthquake levels the West Coast of the US and kills the love of Cassie's (Sarah Wayne Callies) life, she makes a promise to him to find and protect his daughter, Mckayla (Tati Gabrielle), who, prior to the quake, ran away in anger, blaming Cassie for breaking up her parents' marriage. However, the earthquake was so powerful it caused a giant island to rise 26 miles off the coast. Cassie discovers McKayla is on the island and, with the help of seemingly good Samaritan Wayne Sharp (David Harbour), they navigate through the chaotic aftermath of Los Angeles to the island. Others have also made their way to the island, leaving behind their old lives in hopes of starting something new. As tribalism sets in and boundaries are drawn, the islanders will discover something else has risen with the island, something that threatens them all. Told from the perspective of Cassie and Wayne's interrogation onboard a Naval cruiser three weeks later by Captain Mark Dover (Jeffrey Dean Morgan), we will discover the story of what happened on the island, why Cassie and Wayne are the only survivors, and whatever killed everyone on the island is now starting manifest itself on the ship.
