The struggle of a young doctor-to-be in finding his true calling while dealing with romance and friendship as a "ko-ass" or pre-med.

Riva (Adipati Dolken) entered the Faculty of Medicine just because she joined her friend, Evi (Tika Bravani), her best friend since high school. When the co-ass program was started, Riva began to be close to Vena (Aurélie Moeremans), a beautiful co-ass of the hospital's shareholders, causing the relationship between Riva and Evi to crack, because each was ashamed to admit that they were more than friends. As a result of the mistake of the ridiculous mistake he made, Riva was blacklisted by the Professor. He began to hesitate and questioned his choice to become a doctor. But after seeing the death of a patient, then Riva was aware of the true meaning of the call and responsibility for his choice to become a doctor. Towards Evi's departure from his life, Riva also realized that what they had all this time was love.—Mwd
