Fatal Affair (2020) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Fatal Affair (2020), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

Ellie Warren is a highly accomplished attorney who shares her life with her husband, Marcus Warren, who is on the road to recovery following a devastating car accident. They have recently relocated to a beautiful coastal home, leaving behind the busy streets of San Francisco, particularly now that their daughter Brittany Warren has embarked on her college journey.

Amidst this transition, Ellie encounters her firm’s new tech consultant, David Hammond, a familiar face from her college days. David, however, is grappling with his own demons, undergoing anger management therapy due to a troubling incident involving a woman named Deborah. Initially, Ellie and David meet for drinks, but the encounter escalates inappropriately in a club’s restroom, despite Ellie trying to maintain her boundaries.

What follows is a harrowing ordeal as David begins a troubling pattern of obsessive behavior—stalking her through relentless phone calls, text messages, and unwelcome surveillance of her new home. He even breaks into her house and hacks into her security system, all while managing to charm Ellie’s friend Courtney. Despite Ellie’s adamant warnings for David to keep his distance, he continues to cross boundaries.

The situation becomes dangerously serious when Ellie learns from a former college peer that David is suspected of murdering his ex-wife Deborah and her new partner shortly after their divorce. Alarmed, Ellie sends an email detailing her suspicions to Courtney, but David swiftly deletes it. The situation spirals further when Ellie is horrified to discover David golfing with Marcus.

In a desperate bid to seek the truth, Ellie persuades the concierge at David’s apartment to grant her access, uncovering a shocking revelation—photos of Deborah and herself taken without her knowledge stored on David’s computer. Just as Ellie calls Courtney to alert her about what she has found, David arrives at Courtney’s home and brutally attacks her, leaving her injured and in need of urgent medical attention.

With the police now on the hunt for David, he resorts to a sinister ploy, attempting to convince the public of his own suicide by setting a homeless man on fire alongside a fake note. Yet, authorities soon recover crucial evidence that links him to the murder of his ex-wife.

One fateful night, Ellie receives a message—presumably from David—urging her to come to her office to sign some documents. Upon arrival, she discovers her assistant has met a tragic fate. Filled with terror, Ellie rushes home to call the police but is confronted by David, whom she bravely knocks unconscious with a vase. The climax unfolds as she uncovers the horrific scene of her daughter Brittany’s boyfriend Scott lifeless and her family—Marcus and Brittany—held captive.

In a final showdown as the police arrive, David kills an officer in the chaos that ensues. As the battle erupts on the beach’s cliffs, Ellie and Marcus confront David, leading to a dramatic conclusion where he falls to his own demise.

Months later, as life begins to return to normal, Ellie and Marcus prepare to send Brittany back to school, signaling a new chapter in their lives while putting the traumatic events behind them as their house is put up for sale.

Ending Explained – What Happens at the End of Fatal Affair?

Still wondering what the ending of Fatal Affair (2020) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.

The ending of Fatal Affair leaves viewers in suspense regarding David’s fate after he falls from the cliff. Although it appears he crashes onto rocks or the ground below, the film intentionally keeps his true outcome ambiguous. The cliff overlooks the ocean, so David could have either fallen into the water or onto solid land—each possibility opening different futures. His deliberate release of Ellie’s hands could mean he’s willingly sacrificing himself, perhaps to die and escape his torment, or he might think he can survive the fall and return later to continue his threats.

The final scenes, set two months later, show Ellie, her husband Marcus, and their daughter Brittany moving on—Brittany heading off to college and the family preparing to sell their house. Everything suggests a resolution and closure, hinting that the danger may be over. However, the movie’s choice not to show David’s body or his landing leaves a lingering doubt. Since he faked his death once before, there’s always the possibility he survived and could reappear. The open-ended conclusion leaves the door wide open for a sequel or further story, leaving us contemplating whether David truly met his end or if he’s still out there, plotting his next move.
