Mike and Danny become reluctant hitchhikers, looking for a lift to anywhere. They are picked up by apple farmer Walter Ling and his niece Sue-Lin. They end up in Seattle, Washington, location of the 1962 World's Fair. When the uncle is called away on business, Danny persuades Mike to take Sue-Lin to tour the fair. During a visit to a doctor at the fair, Mike falls for Diane Warren, an attractive but stubborn nurse who resists his advances. He gives a quarter to a boy (Kurt Russell) to kick him in the shin so that he can be treated by her. Diane's supervisor then convinces her to give Mike a ride back to his apartment, convinced that his leg is injured. Mike and Diane dine at the top of the fair's Space Needle. However, he also courts Dorothy Johnson.
