Horace MacDonald's career as a Navy SEAL was ended by a hand grenade that nearly tore his leg off. The docs saved his life and even his leg, but they couldn't save his career. Today, this wounded warrior wanders the back roads of America, finding solace in outdoor recreation opportunities while he tries to reacquaint himself with a homeland that has become unfamiliar...even strange...after two decades of fighting to defend her in far off lands. We join Horace for a day of Tarpon fishing in Boca Grande, Florida, on board the flats boat of Captain Hal, a Vietnam veteran fishing charter captain who has befriended Horace. But this day it is not to be. An explosion rips through the sub-tropical Florida morning air, obliterating a nearby fishing boat. Horace breaks off the Tarpon he was fighting so the men can search for survivors in the water. What they find is far more dangerous than a burning oil slick and floating debris.
