Eve (Barbara Anderson) investigates when an old friend, the female member of a folksinging trio consisting of two brothers and a sister, disappears during a San Francisco concert tour. Could this disappearance be linked with the murder of another girl--to say nothing of a sinister drug ring? The key to solving the mystery is a curious geometric configuration called "the quincunx." Cast as the singing Roberts brothers, David Carradine and Michael Blodgett perform "Lonesome Stranger", "I Stepped on a Flower" and "Sorrow of the Singing Tree". ~ Hal Erickson, Rovi
