Interwoven story arcs, shifting time-lines, fine acting and quiet dignity combine to make writer-director John Sayles' "Lone Star" (8: 30 p.m.-11 p.m., Showtime) a don't-miss.
Chris Cooper plays Sam Deeds, sheriff of the Texas border town of Frontera. When a decades-old skeleton is found by the nearby Army post, Deeds' job is to find out who it was. He soon suspects it's the remains of Charlie Wade (Kris Kristofferson), a pretty nasty sort who vanished 40 years before -- to be replaced as chief law-keeper by Deeds' father, Buddy (Matthew McConaughey, seen in flashback), who became one of the town's most beloved citizens.
