Dr. Champ is a sports medical drama about an orthopedic doctor, Kim Yeon Woo (Kim So-yeon), who transfers to Taereung National Village after being let go at her former job for bringing to light her supervisor's malpractice case. Yeon Woo believes that treating athletes is beneath her skill level but has no choice after losing her previous employment due to her divulging her supervisors malpractice case. While at Taereung National Village, where all the Olympic athletes go to train, she meets and becomes romantically involved with Park Ji Heon (Jung Gyu Woon), a young and reckless judo athlete, while also being involved with Lee Do Wook (Uhm Tae Woong), the director of the facility haunted by his speed skating career being cut short by a crippling injury. Complicating the situation more than it already is, the swim coach Hee Young (Cha Ye Ryun), is competing for the romantic attention of Do Wook as well.
