A Hollow Fight is the story of a troubled fat boy named Mike Crow who decides that being homeless is more satisfying than living a typical teenage life. Happily, he takes off from San Diego California and travels aimlessly down Pacific Coast Highway. He fights off weather changes, battles hunger, and searches for nightly shelter.

Months after embarking on an uncertain journey, the adventurer ends up in the Oregon wilderness. Mike climbs hills, talks to animals, builds fire pits, and meanders through monstrous trees as he lives as one with nature. Survival becomes what he believes will be the fight of his life after he runs out of canned goods to eat and can't locate clean water. As he is dying, Mike spots a cargo train and is forced to stab himself for adrenaline.

In Seattle, Mike the bum rescues a girl being attacked; however, he is put in a sticky situation and goes to jail. At trial, he is found innocent and is approached by an older jury member named Ethan Chan, whom happens to be a boxing trainer. As Mike trains for his amateur boxing fight, he learns a thing or two about love when he bonds with the old wisdom of Ethan Chan.
