They've barely seen each other for 30 years. Now they've reunited for a bike tour to Spirit Lake at the foot of Mount St. Helens in Washington State: an old hippie named Cloud Rock and his son Kaleo La Belle, who lives in Switzerland and works as a documentary filmmaker.

The meditative trip becomes a sensitive search for the meaning of life, self-discovery and common ground.
