Maya, an artist, and Noah, a quantum physicist, are happily married.

But beneath the surface of their wedded bliss is a third rail: Serena, the lost child that Noah had with his ex-wife. When Noah gets a call from an eccentric billionaire asking him to participate in a clandestine project aiming to unravel the secrets of time and consciousness, the couple agrees to relocate to the Janus Lab, deep in the desert, and Noah finds himself drawn into a dangerous kind of time travel that could result in seeing Serena again.

But Janus lab is not what it seems, and soon Noah and Maya are drawn into its dangerous web, where they must grapple with their pasts and plumb the depths of human connection to find their way back to one another.
