Who Are The Main Characters In Unbelievable?

Unbelievable' is such a gripping series, and its characters really stick with you long after the credits roll. The two main protagonists are Marie Adler, played by Kaitlyn Dever, and Detective Grace Rasmussen, portrayed by Toni Collette. Marie's story is heartbreaking—she's a young woman who reports being raped, only to be disbelieved and even accused of lying by the police. The way her trauma unfolds is painfully realistic, and Dever's performance is absolutely gut-wrenching. On the other hand, Grace Rasmussen is this no-nonsense, seasoned detective who teams up with another investigator, Karen Duvall (Merritt Wever), to uncover a series of linked rapes. The contrast between Marie's vulnerability and Grace's hardened resolve creates such a compelling dynamic.

What I love about 'Unbelievable' is how it doesn’t just focus on the crime but also dives deep into the emotional toll on everyone involved. Karen Duvall, played by Wever, brings this quiet intensity to the table—she’s methodical and empathetic, a perfect counterbalance to Grace’s more abrasive style. The series also sheds light on how systemic failures can retraumatize victims, especially through Marie’s arc. It’s one of those shows that makes you furious at the injustices but also hopeful because of the tenacity of people like Grace and Karen. The way their partnership evolves feels so organic, and by the end, you’re rooting for them as much as for Marie.

Marie Adler and Detective Grace Rasmussen are the heart of 'Unbelievable,' but the supporting cast adds so much depth. Marie’s journey is brutal—her initial report is met with skepticism, and seeing her life unravel because of it is devastating. Meanwhile, Grace is this brilliant but emotionally guarded investigator who teams up with Karen Duvall to crack the case. The chemistry between Collette and Wever is fantastic; they play off each other like real partners, with all the friction and mutual respect that comes with the job. The series does an incredible job of highlighting how differently these women navigate the same nightmare.
