Obsessive bird egg collector J.P. Whittier is determined to obtain the eggs of a newly discovered species of bald eagle nesting high up on the private island of reclusive Vietnam veteran Jim Malden. Whittier hires mountaineer Mike Walker to pose as a photographer and win Malden's confidence in order to gain access to the eggs. Subplots include locals seeking revenge on Malden after being caught hunting on his island without permission and Malden's inability to express his affection for local store owner Stella Clayton and her son Adam. At Walker's suggestion, Malden visits Stella to tell her how he truly feels. Walker uses the opportunity to scale the mountain where the eggs lie, only to fall victim to his conscience when his goal is within his grasp. Malden, Stella & Adam are united at the end, while Walker provides a local reporter with a scoop about Whittier's illegal hobby.
