Grisù has never had any doubt about what he wants to be when he grows up: he wants to be a firefighter! Admiring these brave men and women who brave dangers to save others, Grisù sees them as true heroes. His Father Fumé doesn’t understand his son’s vocation: Grisù is a dragon… is there anything more natural than breathing fire? Every day, Grisù goes to the fire station and asks for a job there but the reply is always the same: all positions are filled… However, Grisù can always depend on the support of his friend Stella, and of course her father David the Fire Chief and the Mayor of the town find him another role. Because everyone in the town is sure of one thing - Grisù is a dragon who is capable of achieving great things!
