Dominic and Kira Silverstone, a wealthy couple, realize their success can help fight crime. They create vigilante identities, working in secret to lower crime and protect their city from corruption, while balancing their public lives.

Dominic Silverstone leads a double life as Nova, also known as The Amethyst Knight, a vigilante determined to rid his city of crime. His wife, Kira, occasionally joins him at night as Celestia, The Sapphire Dame. Together, they use their wealth, skills, and technology to combat criminals and restore order. But their latest challenge comes in the form of a villain named Grim, a twisted figure obsessed with exposing the corruption of the city's elite. Grim specifically targets corrupt "Bacon Hairs," a group he believes hides behind a mask of innocence. As Grim's vendetta escalates, Dominic and Kira must work together to stop him before he brings chaos to the entire city. Balancing their vigilante lives with their public personas becomes more difficult as Grim draws closer to uncovering their own secrets, forcing them to confront not just the city's corruption but their own vulnerabilities.
