Betrayal: Dirty Secrets Uses Internal Affairs Footage to Tell Season 4's Story

Hulu's fourth season of Betrayal is not notable simply because it arrived on August 4. Betrayal: Dirty Secrets pairs the account of a family discovering a police officer's concealed conduct with footage from the Colorado Springs Police Department's internal affairs investigation. That combination of firsthand testimony and investigative material is the clearest reason this three-part story is different from a routine streaming-date announcement [S1][S2][S3].

All three episodes are available together in the United States on Hulu and Hulu on Disney+. The simultaneous release is confirmed by the current distribution reporting, while Disney's own announcement confirms the season title, date, platforms, and three-part format [S1][S2][S3][S4].

Whose story Dirty Secrets tells

The season centers on Karoline Borega and her marriage to Joel Kern, who served as a Colorado Springs police officer. Hulu's press materials describe Kern as having led a hidden life involving abuse of power and misconduct, and frame the season around the effect of those disclosures on Borega's family and her effort to rebuild her life [S1][S2][S3].

That attribution matters. Dirty Secrets concerns real people, so the article should not turn a program synopsis into an independent finding. What the locked sources establish is how Hulu and the producers describe the season: Borega's account is the organizing perspective, and Kern's alleged conduct is examined through the consequences described by the people interviewed [S1][S2][S3].

The internal affairs material is the substantial new detail

The season includes interviews with Borega, her daughter Nicole, one of Kern's former lovers, and Betrayal podcast host Andrea Gunning. The announced inclusion of footage from the police department's internal affairs investigation gives the series a second evidentiary layer beyond retrospective interviews [S1][S2][S3].

That does not make the documentary equivalent to an official adjudication. It does mean viewers are being offered material connected to the department's own inquiry, alongside accounts from people directly involved. For a franchise built around intimate stories of deception, access to that institutional record is the part of Season 4 most likely to change how the central story can be examined [S1][S2][S3].

The locked sources do not specify how much internal affairs footage appears, which stages of the inquiry it covers, or how the program contextualizes it. They also do not provide the investigation's complete findings. That boundary is important: Season 4 can be described as offering access to investigative material, but not as delivering a definitive official account. Viewers will have to assess how the production connects that footage to the participants' recollections and whether it clearly distinguishes the documented record from personal testimony [S1][S2][S3].

Why the three-part structure matters

Disney, Media Play News, and What's On Disney Plus all identify Dirty Secrets as a three-part season. The compact format gives the production room to connect Borega's discovery, the family impact, the other interviews, and the internal affairs footage without presenting the premiere as a weekly procedural update [S1][S2][S3].

Glass Entertainment and ABC News Studios produced the season. Its full release is now available, but the commissioning value is the access it promises rather than the calendar fact: a firsthand family account placed beside footage from the investigation into a police officer's conduct [S1][S2][S3][S4].
