"Lioness" tells the true story of Lance Corporal Leslie Martz, a US Marine who was stationed in Haditha, Iraq, according to The Hollywood Reporter.
Martz was sent to Afghanistan as a leader of a Female Engagement Team and tasked with the dual mandate of gaining the trust of Afghan women by equipping them with necessary skills for independence but also secretly extracting information from them about their Taliban husbands.
Rosalind Ross, one of the writers of the El Rey Network's action series Matador, has penned the script. She will also act as a producer.
No director has been attached at this stage.
Page will next be seen in "Freeheld", the same sex civil rights drama opposite Julianne Moore and Michael Shannon, which Lionsgate will release on October 2. She is currently filming the indie drama "Tallulah" with Allison Janney.
