It's Spring Break and the gang wants to go to Mammoth but instead decides on Palm Springs... all go, except Brenda who finds a diary in her window seat, which belonged to a girl names Wendy Edwards back in 1968. As she reads it, she inserts her friends as characters in the diary. She imagines Andrea as a hippy, Steve as Ronnie, and Dylan as Peter Brinkley, who is against the war. David is Seth who wants sex from Mary Anne Bailey, played by Donna, and he gets it. Brandon plays Wendy's brother, Will, who dies in the Vietnam War, and Kelly plays Michelle who overdoses on LSD in 1971. The diary includes the numbers 134, 10, 66, and 72 which Brenda finds out to be the roads to Woodstock after she tracks down and meets the real Wendy.
