The movie centers on an I.T. consultant-turned-hacker (James Frecheville) who turns a wealthy businessman’s (Brosnan) life upside down when their relationship runs sour, stalking his daughter and threatening his family, business, and life.
The 26-year-old singer, in September, shared a picture of Austin from a scene of the film.
