Ron Mann's Go Further is a documentary observing the escapades of Woody Harrelson and his comrades as they travel from Seattle, Washington, to Los Angeles, California.

In an attempt to spread a message of change in order to better the planet, Woody and his companions—"a yoga-teacher, a raw food chef, a hemp-activist, a junk-food addict, and a college student who suspends her life to impulsively hop aboard"—speak at numerous universities and visit various environmentally important sites, as their journey weaves on and around Route 101.
