Vincent suffers from Tourette's Syndrome and, after his mother's death, is institutionalized by his father. He ultimately escapes with two fellow patients -- an anorexic named Marie and the obsessive-compulsive Alexander. His mission is simple. He wants to bury his mother's ashes in the seas off Italy, as was her dying wish.
But to get there he and his friends steal their doctor's car. If caught, it could all be quite an embarassment for Vincent's politician father. But the real problem is that Vincent and his friends threaten to drive each other crazy.
