You don't need to break out of the prison where your parents told you to live: you can simply walk away as its doors are always open!
Tom and Lola are both 9 years old. Since their birth, they live prisonners in a bubble, with the world around them forbidden. Their little world is professor Vaneau, their 'prison guard' Hélène, his assistant caring as mother, and Catherine, Tom's mother. Tom and Lola dream of a country where air is pure: Alaska... A movie for young and old, loving and poetic.
