Twin brothers Quentin and Antoine escape from their father's bakery to attend the funeral of the mother they never knew.
As they hitchhike towards Barcelona, old grudges between the two teenagers resurface.
Antoine resents the friendships that his brother makes on the road, while sensitive Quentin is frustrated by his brother's jealous and possessive behaviour.
Increasingly hostile, Antoine cruelly ditches Quentin but he soon realises that he can't make it to Spain without his brother by his side.
