Airborne Gold

Dan Long, a melon farmer, hires Chuck and P.T. to help look over his fields, which straddle the Mexican border. Unbeknownst to Chuck and P.T., however, the farmer is actually using their Bell 47 to ferry gold bars across the border! An informant tips his hand and the authorities are called in --- but not before some of Long's double-dealing henchmen grab the gold and make off. Now Chuck and P.T. must head after the crooks and recover the stolen loot.
