Joe Doyle (Daniel Zovatto) is a hitman who lives with his mother, Gloria (Academy Award nominee Cathy Moriarty). By day he stalks his victims, by night he watches old movies and Instagram stories in his room. While casing city council member, Ed Terzian (Tom Segura), Doyle becomes attracted to the councilman's assistant, Mia (Tilda Cobham-Hervey). When she accidentally witnesses Doyle murder her boss, Doyle becomes conflicted about what to do with her -- so he takes her back to his house until he can figure things out. Concerned only for her son's life, Gloria wants Mia dead, while Doyle's employers, Lee (David Proval) and son James (Buddy Duress), pressure Doyle about the missing girl. But there is more than meets the eye with Mia, leaving Doyle to navigate a situation he's never encountered – falling in love.
