When a grandmother’s hidden past collides with her granddaughter’s secret future and her daughter’s angry present, can the love of three generations be enough to surmount decades of deceit? The story “Snapshots” tells is set in motion when a single roll of undeveloped film is found in an old camera. Using extended flashbacks to the early 1960s, the film explores the interconnected lives of matriarch Rose (three-time Oscar nominee Piper Laurie in the present, Shannon Collis in the past), daughter Patty (Brooke Adams), and granddaughter Allison (Emily Baldoni). Based on co-screenwriter Jan Miller Corran’s own family’s story, “Snapshots” is directed by Melanie Mayron. First known as an actor — in projects ranging from the pioneering indie film “Girlfriends” to TV’s iconic “thirtysomething” — Mayron has since established a parallel career as a talented and prolific director of film and television (recent work includes “Jane the Virgin,” “GLOW,” and “Pretty Little Liars”).
