Harry Walker (David Janssen) is a helicopter traffic reporter in Salt Lake City who's never quite gotten over the time he spent flying during World War II -- a former combat pilot, he sees the world passing him by amid complacency and his own life reduced to boredom and bittersweet nostalgia for the best of times, when he was working for a cause that mattered (and there were causes that mattered). He chances on a brutal armored car robbery and helps the police give chase, and suddenly finds himself in the thick of the action when the robbers -- who have taken a woman hostage -- switch from a getaway car to a chopper. And when the getaway chopper tries to ram him, that's all it takes to get Walker into a cross-country aerial pursuit into the Utah desert in a duel to the death.
