Kate wakes up in her kitchen, having no idea where she had been for five hours. The only clue she has is a note she left for herself on her desk, stating that she was going to see someone named Naomi.

With some investigation, she discovers Naomi is a therapist she has been seeing for months to discuss her blackouts and dissociation. However, she hasn't been attending the sessions as Kate, but under a different name: Veronica.

Once she realizes she is experiencing dissociation, Kate takes a deep dive into her life, trying to uncover her alters and make peace with the people she shares a headspace with.

As she unlocks secrets hidden even from herself, she has the support of her best friend, Brielle, and her therapist, but not everyone is out to help her.
