Student pilot Kay Galloway sights a UFO while flying a T-34 and recklessly dives to Earth trying to chase it, and then faces expulsion from school and humiliation from her fellow students. Because of the unique configuration of the T-34, Galloway's teacher doesn't see the UFO, and doesn't believe her story. Accused of buzzing a restricted area, Galloway is brought before an honor board at school which could recommend her expulsion. With no other witnesses to her sighting, Galloway is certain she'll be expelled, not realizing her boyfriend, Douglas Detwiler, is keeping important information from her and the honor board.
