Walt Disney and Art Linkletter co-host a live celebration of Disneyland's 1959 expansion that consisted of the debuts of Matterhorn Bobsleds, the Disneyland-Alweg Monorail, and the Submarine Voyage, a project so massive that it was called "The Second Opening of Disneyland". Highlights include a mammoth, star-studded parade and the official launching of the Disneyland submarines by U.S. Navy officers. Among the guests are then-Vice-President Richard Nixon and family, Clint Eastwood, and Meredith Willson, who leads the Disneyland band in his own "76 Trombones." Sponsored by Kodak, the commercial spokespersons include Ozzie and Harriet Nelson.

The audience visits WED Enterprises and sees how Disneyland attractions are created, including Pirates and the new Tomorrowland.
