Hitwoman: Saga of 717

Pitch:
A genetically engineered super soldier known only as 717 escapes from a covert underground facility after fragmented memories of her past resurface. Now on the run across Europe, she must outwit and outfight the world's deadliest assassins, sent by the shadowy organization that created her, as she races against time to uncover the truth about her identity and reunite with the family she barely remembers.

Plot Summary:
Act 1: The Vault
In the depths of a secret underground facility known as "The Vault," nine female super soldiers are being trained to become the ultimate assassins. Among them is Number 717, a lethal and highly skilled operative with no memory of her past, only fragments of a life she can’t fully grasp. Unbeknownst to her, she was once Angela Shultz, a girl captured at age 13 from a scientist in East Germany who originally designed the program.
717 is the last of her kind, having killed the other nine in brutal training sessions. The facility's overseers, a shadowy organization, continue to condition her, erasing any flicker of memory that could compromise her lethal efficiency. However, during a routine memory wipe, a glitch occurs, and 717 begins to experience visions of an address and brief flashes of her family—a mother, a father, and a younger brother.
