Cherry Laine (Olivia Cooke) is doing her best to hide a mysteriously dark past from her new boyfriend, Daniel (Laurie Davidson). But good luck keeping it from Daniel’s intuitive, overprotective mom, Laura (Robin Wright). That conflict sets in motion one deadly rivalry in this six-part psychological thriller premiering in full on Wednesday, September 10, on Prime Video.

Based on Michelle Frances’ novel of the same name, The Girlfriend follows Laura, a woman who seemingly has it all: a glittering career, a loving husband, and her precious son. Her perfect life begins to unravel when Daniel brings home Cherry, a girlfriend who changes everything. After a tense introduction, Laura becomes convinced Cherry is hiding something. Is she a manipulative social climber, or is Laura just paranoid? The truth is a matter of perspective, and both women go to extreme lengths to prove that their truth is the one to believe.
