Daredevil is based on marvels comics and is made into a tv series by netflix.Its based on aboy who lost his eyesight in an accident where some chemicals got into his eyes not only stealing his vision but giving him an upgraded sense.His senses are so strong that he could hear something from a far out, judge your move from your body temprature and a whole lot of stuff like this.
Mathew Murdock is also a lawyer who with his lawyer buddy Foggy tries to solve crimes in the hells kitchen which is flooded with mobs.
They know something really big is cooking in the hells kitchen and they finally come to know the real man behind it, which is Fisk.I wont give any more spoilers now but just would say that you are probably missing out on a great tv series and should really go and watch it ASAP.
