“I killed him, but it wasn’t really me…”
Sofia, a young woman with multiple personalities, has been arrested as the prime suspect in the assassination of a presidential candidate.
Psychiatrist Philip is assigned to interrogate her. Forced to conduct the investigation remotely, he must piece together the truth through surveillance footage, recorded evidence, and conversations with the personalities living within Sofia.
Behind the security cameras await four distinct personalities, each born from Sofia’s traumatic past and each guarding secrets of their own. As Philip earns their trust, he begins unraveling the events that led Sophia to become the prime suspect in one of the nation’s most shocking crimes.
Every conversation shapes the investigation, and every deduction influences the fate of Sofia’s five personalities in this multi-ending narrative mystery adventure.
