“Maternal Secrets” (** out of four) was a murky thriller about a U.S. Senator (Sean Stolzen) and his girlfriend (Kate Mansi) on vacation in Bermuda when he suddenly vanishes; the girl then runs into his bizarre mother (Kelly McGillis) on the island and begins to suspect she knows more about his disappearance than she’s letting on. Lots of twists and turns but little logic or plot continuity and even less to care about because the central mystery really isn’t all that intriguing. Try and see if you can recognize McGillis here, if you haven’t seen her in a while.
