La Brea, a science fiction drama TV series, premiered on NBC.
A massive sinkhole opens in Los Angeles' La Brea Tar Pits, swallowing people and objects into a mysterious primeval world beneath the city.
Survivors who fell into the sinkhole begin to explore and face dangers in a prehistoric landscape filled with ancient creatures and unfamiliar terrain.
The survivors create a camp to organize themselves, establish safety, and plan for survival and rescue in the primeval world.
The group realizes that the sinkhole is linked to a time anomaly causing the blending of prehistoric and modern elements.
Survivors encounter dangerous prehistoric creatures such as saber-tooth tigers and giant sloths threatening their safety.
Attempts are made to send signals or messages back to the surface world for rescue using primitive and improvised methods.
Investigations hint that the sinkhole may have been caused by experiments or events involving strange energy anomalies in the city.
Tensions rise and the group divides over leadership and survival strategies, complicating rescue efforts.
A plan is formed to find a way back to the surface or another timeline to save the trapped survivors.
