Back in the day when stunt cyclists soared to the zenith of the zeitgeist, a most unusual circus family roamed the byways and highways of Saturday morning. Led by eldest sibling Ernie Devlin (voice of Michael Bell), a daredevil stunt cyclist, aided by master mechanic younger bro Tod (voice of Mickey Dolenz) with little sister Sandy (Michelle Robinson) handling publicity, the Devlin clan travels across the country with a traveling circus in a too-cool camper, investigating a different kind of cartoon mystery -- that of the human condition. Thanks to the care and understanding of circus owner Hank (voice of Norman Alden), the Devlins have all the space they need for stunt-works and good-works. Among the problems tackled by the clan in this decidedly more adult- toned Hanna-Barbera classic are traumatic flashbacks, undocumented child immigrants, satanic rock idols and child runaways. 2-Disc, 16-Episode complete series collection.
