La Brea - - Season 3

Here’s a story treatment for La Brea — Season 3 , picking up from the massive cliffhangers of Season 2 and aiming to give the show a thrilling, emotional conclusion.

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.

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.

Josh must reopen the rift — but doing so will cost him years of his life. La Brea - Season 3

We open moments after Season 2’s finale. Eve (Natalie Zea) watches in horror as the portal to 2021 closes, leaving her son Josh (Jack Martin) stranded on the other side. Meanwhile, Gavin (Eoin Macken) clutches his head — a new, violent vision floods his mind: not of the past, but of a future Los Angeles consumed by a second, deadlier sinkhole event.

Josh finally arrives through a collapsing rift, aged ten years (now played by a new actor, mid-30s). He looks at Gavin and Eve: “Dad… I saw how this ends. Only one of you can go home. The rest have to stay in the past — or time breaks.”

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.” Here’s a story treatment for La Brea —

Battle erupts at the cavern. Lucas sacrifices himself to destroy Maya’s command center, trapping her in a collapsing side rift (her fate left ambiguous). Ty and Veronica lead the survivors in a desperate last stand.

They’re attacked by a new tribe: , humans who worship the rift technology and believe closing it will unmake existence. Their leader, Zane (played by Alex Meraz), captures Sam and Veronica. Zane reveals he is also “rift-touched” — a descendant of the Ancestors — and that Eve’s return was a trap. “The rifts chose your family, Gavin,” Zane sneers via a psychic link. “But you’ve been closing doors that should stay open.”

Cut to black. A single sinkhole opens in the middle of a desert… and a tiny flower falls through. In 10,000 BC, the survivors — led by

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.

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”

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.

Riley’s vision guides them to an underground cavern beneath the original sinkhole — the resting place of the first Ancestor, a being who sacrificed herself to stabilize time. The “temporal anchor” is her preserved heart, pulsing with energy.

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.
