La Brea - Season 3 -
The survivors embrace their new lives. Sam becomes a history professor, Ty an architect, Veronica a trauma surgeon. Josh, now older than his parents, struggles to belong — but finds peace in remembering.
In 10,000 BC, the survivors explore the bunker and activate a holographic map. It shows multiple rifts across history — and a countdown: 72 hours until a “cataclysmic merge” where all timelines collide.
Back in 2021, Josh finds himself alone in a quarantined L.A. The sinkhole site is now a high-security government lab run by a ruthless new director, (new series regular, played by Nimrat Kaur). She believes Josh’s DNA — part of Gavin’s “rift-touched” bloodline — is the key to controlling the ancient anomalies.
Josh discovers another survivor trapped in 2021: (recurring actor), a scientist from the 1950s who stepped through a rift decades ago and has been hiding in plain sight. Paulo reveals the truth: The rifts are caused by a decaying “temporal anchor” buried deep beneath La Brea, a device built by an advanced prehistoric civilization (the “Ancestors”). If it fails, all of time collapses. La Brea - Season 3
Josh must reopen the rift — but doing so will cost him years of his life.
Gavin, Ty, and Riley stage a rescue. In the fight, Riley is fatally wounded — but before she dies, she touches the bunker’s core and sees the entire history of the rifts. Her final words: “It’s not a machine. It’s a grave .”
Gavin refuses. But Eve whispers: “I already died in one timeline to save you. Let me save everyone now.” The survivors embrace their new lives
Gavin, Josh, Sam, Ty, Veronica, and the remaining survivors use the repaired anchor to open a final rift — not to 2021, but to a new timeline where the sinkhole never happened. They step through, arriving in a sunny, peaceful Los Angeles. No disaster. No scars. They reunite with their loved ones who never knew they were gone.
Eve makes the choice. She merges with the heart, stabilizing time but becoming a living part of the cavern — conscious, eternal, watching over all timelines. She speaks one last time through the rift: “Build a village. Live. I’ll be here when you dream.”
Eve, now haunted by her own visions, realizes she’s the biological echo of this Ancestor (explaining her survival and connection to Gavin). To repair the anchor, she must physically merge with the heart — an act that will erase her from existence in all timelines. In 10,000 BC, the survivors explore the bunker
But Gavin pauses at the edge of the rift, looking back. He sees a vision of Eve, smiling, standing beside the heart. He whispers, “I’ll find you again. In every time.”
In 10,000 BC, the survivors — led by Sam (Jon Seda), Ty (Chiké Okonkwo), Veronica (Lily Santiago), Riley (Veronica St. Clair), and a guilt-ridden Lucas (Josh McKenzie) — realize the aurora borealis that brought Eve back has vanished. They’re trapped. But a seismic tremor opens a chasm near the village, revealing a buried military bunker from the 1950s.
10,000 years later, in the cavern, an archaeologist discovers the heart. She touches it — and hears Eve’s voice: “Tell them we made it home.”
The survivors of the sinkhole discover that the 10,000-year gap isn't just a place — it's a battleground for the future of humanity. To get home, they must unite with an unlikely ally and make the ultimate sacrifice. Episode 301: “What the Rift Took”
