Alone with his girlfriend Diane (Susan Egbert) in the kitchen, Jeff bemused about changing people""s tastes and dreams:I did a thing about suicides of the American Indian.Charlie objects to her hair-brained, suicidal scheme:Charlie: There""s only one little thing wrong with your idea.You beat me by one second, one second.That""s very hard for a man of my intelligence to handle...No TV, no newspapers, just you and me...I""m still young enough to whip your butt, Stallion...You fight great, but I""m a great fighter." In their sparring match as they danced around the ring, the camera froze on their first punches aimed at each other (and dissolved into a LeRoy Neiman portrait), and the film concluded with the tune "Eye of the Tiger".When they were pursued by another helicopter in a field of power-generating windmills, Ethan discovered that an explosive, time-release capsule had been implanted into Lindsey""s skull through her nasal cavity - it had recently been activated and was ready to detonate.
