Billed third, Spencer Tracy plays Lt. Col. James P. Doolittle, who led the bombing raid over Tokyo. Most of the footage concerns pilot Ted Lawson (Van Johnson), who loses a leg while escaping from China after the attack; other subplots concern the meticulous preparations for the raid, and the individual exploits of those Doolittle flyers who crashed into the sea or were captured by the Japanese. ~ Hal Erickson, All Movie Guide
