A medical drama where doctors with completely different values, personalities, and ages, spend their days and nights facing life and death, creating bonds like no other.

So she decides to work as a night doctor. Living in a dormitory near the hospital, she begins to work with great enthusiasm, but the harsh reality that awaits her is far from the ideal she had originally envisioned.

She is highly ambitious and more passionate about saving lives than anyone else, but because of her strong feelings, she sometimes lacks composure and becomes emotional..
