Andrew Niccol will be directing and the film is set to star Hannah's Saoirse Ronan as Melanie Stryder.
Deadline, which has the exclusive report on the Open Road acquisition, describes the plot as follows: "[Melanie Stryder is] one of the last humans putting up a fight against an alien species called Souls, parasites that invade human bodies, fuse to each person's consciousness and systematically erase their personalities. Melanie is captured by the aliens and implanted by a Soul called Wanderer. While Wanderer's goal is to get Melanie to give up the remaining pockets of humans, the alien finds Melanie to be unique in her unwillingness to surrender her consciousness. Wanderer is so overwhelmed by Melanie's memories and feelings that she is driven to reconnect with Melanie's old life, which includes falling for Melanie’s boyfriend. The result is a complex, romantic and emotional human/alien love triangle."
