When Jill Kelly, an old flame of Jim's, comes into his life again, she asks his help in testing a new kind of parachute she feels will be worth much money if perfected. Ted, however, feels the chute is impractical and unsafe, and tries to keep Jim from falling prey to Jill's persuasions, who ultimately cares more for her money plans than for Jim's life.
While instructing their pretty client Tanya Rovag, Ted and Jim become involved in trying to save her father's life from assassination by Communists, who are unwilling to let him publish the political exposé he has been secretly writing in the mountains.
After a recent health scare, Nobel-Prize-winning author and former Korean War correspondent Aaron Sparks asks his friends and comrades-in-arms Ted and Jim to teach him how to skydive, for research for a new novel. But is that the real reason for his interest in this dangerous sport?
