Eric Heisserer has written the script, which is adapted from a short story by 'Nebula' and 'Hugo' Award-winning author Ted Chiang, said The Hollywood Reporter.
The story is set in motion when alien crafts land around the world, and an expert linguist, to be played by 40-year-old Adams, is recruited by the military to determine whether they come in peace or are a threat.
As she learns to communicate with the aliens, she begins experiencing vivid flashbacks that become the key to unlocking the greater mystery about the true purpose of their visit.
