Almost-Captain Gearheardt and his buddy, Almost-Captain Armstrong, are ferrying bodies (live in, dead out) for the CIA's Air America, but they have never forgotten their TOP SECRET orders, given when Gearheardt was delivering pizzas to the Oval Office for the CIA: chopper into Hanoi and buy Uncle Ho a beer. Then either shoot his ass or shake his hand (the instructions get vague at this point).
And so they do, Semper Fi, pausing only to get an aircraft carrier black-flagged for bubonic plague, have an affair with Mickey Mouse, cleverly decode the message sewn into a lusty spy's black panties, commandeer a Russian truck complete with a midget Chinese "Uncle Sam", avenge themselves on a Cuban torturer, and dutifully experience all the Honour and Glory of the next-to-the-next-to-last war that never (God forbid) made the Nightly News. And they do it all for laughs. Because if they were to stop laughing, where would the heartache end?
