Prosecutor Baek Joon Soo gets into a car accident while talking on the phone and is taken to the hospital.

Ha Ra asks Do Chan, a swindler who looks like Joon Soo, to pick something for her instead of Joon Soo.

Joon Soo's recovery takes longer than expected, so Ha Ra makes Do Chan pretend to be Joon Soo.

Do Chan is assigned to a case as a prosecutor, and he has to solve the crime case with the task force team.

Do Chan tries hard to avoid the suspicion of other prosecutors. Tae Woong looks into Joon Soo's accident.

Do Chan finds out about what Joon Soo was after and starts to make a move secretly from Ha Ra.
