A light play isn’t necessarily an insubstantial play. “60 Minutes From L.A.” at the Gene Dynarski Theatre manages some meaningful confrontations in which four women who came to flower in the ’70s discover their smothered identities at a high school reunion party in Lancaster.

It’s not surprising that Lancaster is where first-time playwright Lisa Nichols (also featured in the production) grew up. Her distaste for her hometown is apparent in her play, which dramatizes the folly of resisting change.

…most of the actors are distinctive, beginning with Nichols’ briar patch of a performance and a sweet Jana Howard in the play’s toughest role as a mama’s girl who finally grows up. Eileen O’Sullivan’s hometowner with a stiff upper chin and Elizabeth Hipwell’s thanklessly screechy, dim airhead complete the cast.
