Welcome Home, Roxy Carmichael (movie, 1990)

Movie star Roxy Carmichael is abandoning the bright lights of Hollywood, Calif. and returning to her small Ohio hometown -- at least long enough to dedicate a city building. And now the whole town of Clyde is bracing for Carmichael's return, most of all her now-married old flame Denton Webb and troubled teen Dinky Bossetti. An orphan with few friends, Dinky is convinced that Carmichael is her birth mother, and that the actress will reclaim her when she returns.
