By day, Matt Murdock is a blind attorney who fights for justice in the courtroom, but by night, he becomes a masked vigilante, using his heightened remaining senses to serve justice on the streets of Hell's Kitchen, New York. As a child, Matt was blinded by a toxic waste spill which also gifted him with extraordinary sensory abilities, including a sonar-like radar sense. Driven by the murder of his father, Jack "The Devil" Murdock—a once-honest boxer who was killed for refusing to throw a fight—Matt takes to the streets to prevent others from suffering as he did, adopting the moniker of Daredevil.

Murdock's life becomes intertwined with Elektra Natchios, a skilled martial artist with a vendetta. Their bond grows as they find solace in each other's traumatic pasts. Meanwhile, the city's criminal underworld is controlled by the powerful Kingpin, a formidable crime lord whose identity is unknown to law enforcement. A ruthless assassin named Bullseye enters the fray, with impeccable aim and a penchant for murder, becoming entangled in Kingpin's dark world. Murdock must navigate his life's dichotomy as both defender and vigilante, facing the city's menace that threatens to engulf his own world, while the line between justice and revenge becomes perilously blurred.
