Unbelievable: Netflix’s True-Crime Drama About a Case No One Wanted to Believe

An 18-year-old woman reports that she has been raped in her own home. Instead of receiving immediate support, she finds herself questioned, doubted and eventually pressured into saying the attack never happened.

That painful premise sits at the heart of Unbelievable, Netflix’s limited true-crime drama inspired by the Pulitzer Prize-winning investigation An Unbelievable Story of Rape by ProPublica and The Marshall Project. The series follows Marie Adler, whose experience becomes the starting point for a much larger investigation after two female detectives begin uncovering strikingly similar attacks.

The result is a tense story about trauma, institutional failure and the determination to uncover the truth. Netflix describes the series as being inspired by real events, while the original investigative report documented the real case that inspired the drama.

When did Unbelievable premiere on Netflix?

Unbelievable became available to stream on Netflix on 13 September 2019.

The series consists of eight episodes and stars Kaitlyn Dever, Merritt Wever and Toni Collette in the central roles. Netflix currently classifies it as a limited series and a crime drama based on real-life events.

Is Unbelievable based on a true story?

Yes. The drama draws from the Pulitzer Prize-winning 2015 investigation An Unbelievable Story of Rape, written by T. Christian Miller and Ken Armstrong.

That investigation examined the case of a young woman identified publicly only by her middle name, Marie. In August 2008, she reported to police in Lynnwood, Washington, that a masked man had entered her apartment and raped her.

Marie said she had been tied up, blindfolded and gagged during the attack. But investigators soon focused on inconsistencies in her account. Under questioning, Marie eventually said that the assault might have been a dream and was subsequently charged with filing a false report. She accepted a plea deal.

The consequences went far beyond the criminal charge. Marie lost the sense of independence she had recently gained after growing up in foster care, and people close to her also began questioning whether she had told the truth.

Then, years later, investigators in Colorado encountered cases with disturbing similarities.

Two female detectives, working separately at first, eventually connected their investigations. Their pursuit led them toward a possible serial rapist and, ultimately, back to Marie’s case.

What is Unbelievable about?

The Netflix drama begins with Marie Adler, an 18-year-old living in transitional housing for young adults who had previously been in foster care.

After reporting that she was sexually assaulted by an intruder, Marie is confronted by increasingly skeptical questions from police. The people closest to her also begin to doubt her story, leaving her isolated at a moment when she most needs support.

Meanwhile, the story shifts to Colorado, where detectives Grace Rasmussen and Karen Duvall encounter separate reports involving remarkably similar attacks.

As they compare what they have found, the two investigators begin to suspect that the cases may be connected. Their partnership gradually turns an apparently isolated investigation into the search for a much more dangerous offender.

The series therefore unfolds on two interconnected tracks: Marie’s struggle to deal with what happened to her and the detectives’ painstaking effort to establish what the evidence is really telling them.

The cast of Unbelievable

Kaitlyn Dever as Marie Adler

Kaitlyn Dever plays Marie, the young woman whose report becomes the emotional center of the series.

Her character is portrayed as someone already navigating the challenges of establishing an independent life after growing up in foster care before the reported assault throws everything into turmoil.

Merritt Wever as Detective Karen Duvall

Merritt Wever takes on the role of Karen Duvall, one of the Colorado detectives who begins investigating a case that bears an unsettling resemblance to Marie’s.

Toni Collette as Detective Grace Rasmussen

Oscar-nominated actress Toni Collette plays Grace Rasmussen, the other detective whose investigation eventually intersects with Karen’s.

Netflix announced Collette, Wever and Dever as the series’ leads in 2018, with Collette and Wever portraying detectives whose investigations become intertwined as they pursue a possible serial rapist.

The supporting cast includes Elizabeth Marvel, Bridget Everett and Danielle Macdonald, alongside Dale Dickey, Scott Lawrence, Austin Hébert and Eric Lange.

Who created the series?

Unbelievable was developed by Susannah Grant, who co-wrote the series with Michael Chabon and Ayelet Waldman.

Grant, best known for work including Erin Brockovich, also served as showrunner and executive producer. Lisa Cholodenko directed the first three episodes. Netflix’s production announcement also listed Sarah Timberman, Carl Beverly, Katie Couric and other producers among the executive team.

The drama takes its foundation from the ProPublica and Marshall Project investigation rather than simply using the real case as a loose premise. The original reporting examined how the failure to take a rape report seriously could have devastating consequences for a victim and how separate investigations eventually exposed a broader pattern of attacks.

Is there a trailer for Unbelievable?

Yes. Netflix released an official trailer introducing Marie’s case alongside the investigation led by Karen Duvall and Grace Rasmussen.

The trailer sets up the central tension of the series: while Marie is struggling to be believed, the two detectives are beginning to encounter evidence suggesting that her story may be connected to a much larger pattern.

Netflix continues to list the official trailer alongside the series on its streaming page.

Why the story remains so powerful

What makes Unbelievable particularly unsettling is that its mystery is not built solely around identifying an unknown criminal. Much of the drama comes from watching what happens when a victim’s account is questioned and dismissed.

The original reporting showed that Marie’s experience had consequences extending into her personal life, her housing and her criminal record. Years later, after her attacker was arrested in Colorado, Lynnwood police informed Marie that her record would be expunged and returned the $500 she had paid in court costs. She experienced shock, relief and anger at the news.

The investigation also prompted changes in how the Lynnwood Police Department approached rape reports, including additional training for detectives and greater caution when determining whether a case was unfounded.

That real-world context gives Unbelievable a weight that extends beyond the usual crime thriller. At its center is a young woman whose story was doubted when she needed to be heard, alongside two detectives determined to follow the evidence wherever it leads.

With its eight-episode structure, emotionally difficult subject matter and performances from Kaitlyn Dever, Merritt Wever and Toni Collette, Unbelievable remains a gripping example of true-crime drama rooted in a deeply troubling real case.
