Plot.
In an alternate timeline, dinosaurs have managed to survive the KT Extinction Event and now live amongst humans using disguises. Vincent Rubio is a "Velociraptor" private investigator along with his partner, Ernie Watson, a "Triceratops".
When Ernie's ex-girlfriend's brother is found dead, the incident is dismissed as suicide. However she doesn't believe her brother would kill himself and asks Ernie to investigate ("for free," Vincent observes). When the pair investigate the crime scene, Vincent notices the scent of another dinosaur on the windowsill, concluding it was not a suicide.
At the funeral Vincent talks to a man dressed in a strange suit who belongs to the cult that the deceased had previously joined, "The Voice of Progress." He pretends to be interested in their ideals and gets himself and Ernie invited to a gathering. During the funeral, Vincent detects the same scent from the victim's bedroom, indicating the killer is nearby.
Vincent and Ernie go to the cult meeting where they are told the Voice of Progress' ideals and history: The Voice of Progress is revealed to be both the title of their leader and a collection of dinosaurs who believe that the prolonged use of disguises has robbed the dinosaur community of its unique identity. The cult also believes that humans have caused dinosaurs to see themselves as monsters and humans as normal. While Ernie appears indifferent to the cult's ideals, Vincent is profoundly impacted by the cult's beliefs.
As their investigation continues, Vincent and Ernie come to realize what one man in the cult is planning a dinosaurian revolution by turning cult members into violent, feral dinosaurs and releasing them on the humans. The resulting conflict will force both sides to face each other, and allow dinosaurs to reveal themselves. Though Vincent is somewhat sympathetic to the cult, he disagrees with the idea of a violent revolution (knowing it could end in disaster for both sides), leaving him unsure which side he's on.
Production.
The pilot was originally produced for the Fox network, but was picked up by the Sci-Fi Channel instead.
