Double Back - Screenplay

In the year 2035, Special Agent Lieutenant Daniela Regen, a sharp but self-focused officer in the Android Detection Unit, is pulled from her regular routine into a high-stakes global crisis.
A pioneering scientist, Professor Jaac Erdhart, whose open-source security systems underpin the world’s digital infrastructure, has been abducted and replicated. Tragically the Professor lost his life and importantly the authorities are worried about why the rogue replicant of the professor was sent back in time to the year 2000.
Daniela is tasked with a one-way mission into the past: to identify and destroy the replicant before it can irreversibly alter history and threaten the world’s security.
Daniela arrives in the year 2000. At the young Jaac’s home, Daniela finds herself in the middle of a violent confrontation between two identical men — one human, one replicant. With no way to distinguish them.
Stakes are increased when Jaac’s young son Manny is caught in the middle.
The tension escalates into a chaotic chase - doubling back through corridors and stairwells.
Ultimately, Daniela must make an immediate and irreversible choice. She shoots one of the men, saving the other and seemingly completing her mission.
In the aftermath, Daniela begins to soften, forming a connection with both Jaac and Manny, choosing care over detachment.
But Daniela and Jaac fail to see an unsettling truth.
Manny, playing alone with a doll he calls “Eddy,” reveals a chilling intelligence and control beyond his years. In a final, haunting image, his mismatched eyes—one green, one blue — mirror those of the future antagonist.
Daniela has saved the past.
But in doing so, she may have created the very future she was sent to stop.

Writer Statement

I love easter eggs in films .... and in screen plays. The lead in this screen play in Daniela Regen - a police officer not worth messing with. She is sent back in time by a UN Department Head (whom she IS connected to) called Adelina Green. Why are they ANAGRAMS of each other? Double Back is less of a "Who dunit" than a "Why dunit"! The moral question posed is about the future consequences of our past actions.
