The Rules of 3

The fourteen year old, insecure Twan travels with his twin sister and family to Iceland to get his very ill grandfather Opi Kas back to The Netherlands. There he finds that the unrestrained Opi Kas has the intention to retreat into the mountains, instead of rotting in an old-age home in The Netherlands. To help his Opi, Twan faces the elements of the unruly Icelandic nature and finds his own strength.
