Dong Joo is one of the interns who have joined Geodae Hospital recently. He is notorious among his seniors for disobeying and playing smart. Seo Jung gives advice to him that as an intern, he should follow whatever he's told without thinking. She further explains that the intern should put an elephant into a fridge even if it seems impossible.

Seo Jung suddenly disappears one day after the car accident. Meanwhile, Doctor Do asks Dong Joo to operate a VIP patient and tells him to take it as an opportunity. Dong Joo accepts it but fails. Later on, Dong Joo receives a personnel order and heads to Doldam hospital in Jeongseon, and meets someone there.
