When double-dealing government agent Sidney Preston (Tom Bosley) wanders into Apache Acres, a dusty, roadside cafe in the middle of the Arizona desert, he barely has time to try "the best chili in the Southwest," before he has heart attack. Before dying, Preston tells the assembled customers that he has hidden $4 million and gives obscure clues to the four locations where each million is stashed. The twenty-two hapless adventurers then embark on a madcap race across the Southwest in search of the missing millions.
