Theo, a mentally handicapped young man, works at the airport and lives with his “Auntie” who has been overprotecting him since he was abandoned by his mother. When Michèle decides to find her son in Lisbon, Theo naively agrees to drive her there, but what she doesn’t know is that he only has a car without a license… They then embark on an adventure on the country roads, making us follow people we don’t look at, on roads we never take.
