Synopsis

On a day no different from any other, a straight-A university student Kim Hyun-soo makes the mistake of his life. Just as any other college kid would, Hyun-soo is on his way to hang out with his friends. Late at night, he takes his father's taxi to head over to where his friends are. Hong Gook-hwa, a sad-looking mysterious girl mistakes Hyun-soo's taxi for an on-duty cab and hops in. That was the beginning of everything. All the choices Hyun-soo made that night leads the normal university student to becoming the prime suspect in a violent murder case. While Hyun-soo shivers from fear and the fact that he is falsely accused, everyone still points to him as the only possible murderer. In this hopeless situation, those who stretch out a helping hand are a low-life attorney, Shin Joong-han, and a criminal kingpin who rules the prison food chain, Do Ji-tae. To prove his innocence in any way possible, Hyun-soo gives everything he has to fight against the police and the Korean prosecution.
