Ava (Jessica Chastain) a former drug addict, former US Army spec ops, now an international assassin working for a mysterious organization. Unfortunately she's once again been having doubts about her job, asking victims what they've done to make sure she's assassinating evil people. This is intolerable to the current head of the assassins, Simon (Colin Farrell), who decides to have her be killed accidentally on her next mission or accidentally via another assassin. That puts Simon in conflict with his former mentor and Ava's current handler Duke (John Malkovich).

Meanwhile Ava takes a break and finally returns home to visit her mother Bobbi (Geena Davis), sister Judy (Jess Weixler) and Judy fiancé (and Ava's jilted fiancé) Michael (Common). Ava hasn't been back since she joined the Army, not even for step-dad's funeral but she hated him anyway. It's a strained relationship with her family that she's rarely talked to in years and they have no idea what she really does for a living...

It's an interesting action movie. Delving more into character development and relationships than usual for the genre. As such there are only a few action sequences though they are pretty entertaining. The movie also ends in a bit of a cliffhanger setting up a sequel which I don't really appreciate. But Jessica Chastain kicking ass is way cool so I forgive that.
