When a comet threatens to destroy their planet, the citizens of Hondo send their most decorated soldier, General Trius, to find a new home planet and wipe out the current inhabitants in the process. But when General Trius lands on Earth, he's interrupted by a strange and mystical human invention known as "music." He immediately abandons his mission, starts a family, and launches a one-alien bluegrass act in a tiny Brooklyn bar. Years later, a bumbling assassin named Kevin arrives to get the mission back on track. Although Kevin is no match for the great General Trius, the Hondonians have no intention of calling off their plan to eliminate mankind, so Bill and Kevin must join forces to save Hondo, prevent an intergalactic takeover of Earth, and hopefully get some bigger gigs for the universe's first Hondonian bluegrass duo: Future Folk!
