Mr. Billion

Guido Falcone (Terence Hill), a laid-back Italian mechanic, becomes the sole heir of his recently deceased uncle, Anthony Falcon, and must reach San Francisco within twenty days to sign a document that will allow him to claim his billion-dollar inheritance. However, his uncle's greedy assistant, John Cutler (Jackie Gleason), hires female detective Rosie Jones (Valerie Perrine) to prevent Guido from claiming his inheritance, leading to a wild chase through Italy and the United States. Along the way, Guido must evade kidnappers while navigating this unexpected turn of events in his life.
