An expanded, feature-length version of the Sundance Grand Jury Prize-winning dramatic short of the same title, Jim Cummings' "Thunder Road" tells the story of flawed police officer Jim Arnaud (also played by Cummings), who lives a shambolic life that's somehow made even worse by his mother's passing. His only stability comes in the shape of his daughter, Crystal, who he tries to father--amidst messy divorce proceedings with his estranged wife, Roz --as best as he can.
