Yazan Yahya is born a very quiet boy. He doesn't cry the hungry hyena cry like his big brother, Yakub, or the angry cow cry like his sister, Yara. Yazan grows to become a healthy, active boy, but one thing remains the same: he's still very quiet. He doesn't say a single word, letter, or sound. His parents, Mrs. Yahya and Mr. Yahya, and siblings, Yakub and Yara, worry about him. His mother takes him to a speech therapist. His family plays the speech game with him. Despite all this, Yazan is still a quiet boy. One day, something miraculous happens. Yazan hears his mother crying, asking Allah, "Why doesn't Yazan speak?" Yazan shows her the letter Y, and speaks for the very first time. Everything changes after that. Yazan doesn't stop talking. The joy of hearing Yazan speak quickly becomes annoying, though, especially because he never stops asking why. From home to the local Mosque school and finally to kindergarten, Yazan's eagerness to learn keeps getting him into trouble. Can the family find a solution to Yazan's many questions without discouraging his joyful curiosity?
