Joe Doyle (Daniel Zovatto) is a young hitman following in his father’s footsteps. Quiet and reserved, he is observant and careful, making him very good at what he does. While studying his new target, city council member Ed Terzian (Tom Segura), Doyle develops a distant crush on the councilman’s assistant, Mia (Tilda Cobham-Hervey).
After she walks in on her boss’s assassination, Mia is caught by Doyle who must decide whether to let her go or to dispose of her for good. As Doyle aims the gun at her head, Mia doesn’t flinch, bringing him to a crossroads. Unsure of what to do, Doyle brings Mia to his home where he lives with his overbearing mother, Gloria (Academy Award Nominee Cathy Moriarty), and holds her hostage until he can gain some clarity.
Doyle’s boss, Lee (David Proval), and his son, James (Buddy Duress), start questioning Doyle about the missing girl, and slowly he comes to find that Mia might not be entirely who he thinks she is. Now Doyle must deal with the hardest conundrum of his life, catching feelings for the girl who didn’t flinch.
