Fighter pilot Jake Grafton is adrift following fight in Vietnam. With no place in the States to call home, Grafton sticks from what he knows best: dealing with the world’s most treacherous skies from the cockpit of a Grumman A-6 Intruder. Today, stationed in the South Pacific in the U.S.S. Columbia, Grafton must instruct the Marines aboard the art of soaring from an aeroplanes carrier-a mission that, thanks to the unruly Marine Captain Le Beau, is really as joyless since it is usually dangerous. However when an unexpected foe shows up from above, Grafton and Le Beau must put aside their distinctions and interact to save lots of the lives of most onboard.
