Robert Field heads down to the Trinity River in central Texas in search of river monsters. Alligator gar can grow in excess of 300 pounds and over 7 feet long, and they are notorious for leaping out of the water when hooked. Robert joins Henry Martin and George Saber to give these fish a run for their money, but they prove to be more difficult to land than he anticipated. Watch to find out if he's able to wrangle in one of these prehistoric beasts.
Stay tuned until the end to catch a preview of Part 2, where Robert heads back down to the Trinity with Bubba Bedre, a renowned alligator gar guide that appeared in an episode of River Monsters with Jeremy Wade.
