Foreverland (2011)

William has cystic fibrosis and is struggling to live life to the fullest, choosing to spend his time shopping for coffins. After his friend Bobby dies, William finds himself in a lawyer's office trying to understand the ludicrous conditions Bobby put in his will. William is committed to driving Bobby's ashes to a healing shrine in Mexico. Along for the ride is Bobby's sister Hannah and a home-built car unlikely to go the distance. William and Hannah form a relationship along the Pacific Highway as William struggles with his declining health and the pair fight the obstacles in the path to a miracle.
