Reunion is a 1980 television film directed by Russ Mayberry and starring Kevin Dobson, Joanna Cassidy, and Linda Hamilton.
When he receives a letter informing him about the twentieth reunion of his high school 3000 miles away from Los Angeles, Don is encouraged by Evelyn to attend it, feeling that they could use a break from each other.
Going through the year book, he immediately contacts his high school sweetheart Peggy Sager (Joanna Cassidy), who is now a divorced mother and excited to catch up with Don.
Though thrilled to see her, Peggy's aging looks remind Don of his own decline and he becomes more attracted to her 17-year-old daughter Anne (Linda Hamilton), a high school cheerleader who is in a relationship with the basketball team's star player Steve Cowan (Nick Cassavetes).
Don quickly grows accustomed to his home town, where he is worshiped by the townspeople for being the high school team's star player in 1959, shared with his pals Vincent Scozzola (George DiCenzo), Walker Hanson (Rick Lenz) and Jack Owens (Nicholas Pryor).
