Korea's Mig Alley, the stretch of sky along the Yalu River where American F-86 Sabres and Soviet-built MiG-15s fought some of the first jet-versus-jet battles in history, is the setting for this account of the air war's key engagements. The film centers on Robinson Risner, an F-86 pilot whose combat record against Korean, Chinese, and Russian aviators becomes the spine of the story, reconstructed through archival footage and pilot testimony. It also details a single fight in which Ralph Parr leads four Sabres against sixteen MiG-15s, an outnumbered engagement that stretches into a prolonged dogfight. The film uses that episode to explain how the aircraft itself changed the odds, tracing the shift from the F-86A flown in 1951 to the improved F-86F of 1953 and what those upgrades meant for a pilot in a turning fight. The result is a close look at individual combat decisions inside a war fought largely in the margins of the bigger Korean conflict.
