Dr. Parsa and his daughter, Bahar, are on the way to Khoramshahr to set up a specialized hospital there. It seems their cold relationship is related to this journey. Reaching there, Bahar finds a diary of a girl at her age called Maryam which was written in the same day, 30 years ago; 2 days before the first day of schools, and also the start of Iran-Iraq war! The girlish joy that Maryam describes in the first pages of the diary, the sudden invasion of enemies to their town, and finally her love story which is mentioned in the diary, motivates Bahar to continue reading it. Maryam was in love with a young intern who was working in the town's only clinic. Now Bahar thinks that the intern could be his father.
