Season 1

Episode 3: Helen Makes Contact

Despite Cutter's desperate warnings, Lester remains optimistic that this "anomaly" problem will simply disappear. But the arrival of a vicious sea creature (a Mosasaur) at a local swimming pool is bad news, particularly for a pair of young lifeguards. When the boy's regurgitated body surfaces in a nearby reservoir, Cutter realizes they've got another prehistoric killer on their hands.

More bad news: The newest anomaly is mobile, and it relocates to the depths of the reservoir, where a military diver disappears and another Mosasaur attacks Abby. The team works hard to find and contain the anomaly, but how do you plug a leak in time? Cutter thinks the anomaly runs along a kind of temporal fault line-but without proof, Lester is quick to dismiss his ideas.

Meanwhile, a young mother notices a small leak, which quickly turns into a basement flood. When she sends a plumber down to investigate, she has no idea that a Cretaceous Era predator lurks under the water, ready to pounce.

The anomaly in her cellar later expels the lost diver's corpse, which also bears a message from Helen Cutter. Claudia's suspicions are suddenly confirmed: Helen is still alive-and Cutter has known all about it. Lester delivers the ultimatum: Bring her back, or you're out.

But where on earth are these creatures coming from? Are they an evolutionary throwback? Or perhaps experimental hybrids? As the Cutter and company follow the Scutosaurus, the creature inadvertently leads the team to the answer: A shimmering distortion in the air, into which the Scut completely disappears.

Cutter finally comes face to face with his estranged wife. Helen tries to entice him to stay and explore her brave new world... but what is her real agenda? Cutter rejects her proposition. As he leaves to make his way back through the anomaly, a violent Mosasaur attack nearly maroons him permanently in the past. When he awakes in the present, he finds he didn't come back alone....
