Happily homeward bound...or so they thought... Tommy, Frank, and Chris, members of the Lighthouse Brigade, are back again with a new adventure! Their return trip home is interrupted by delivered subpoenas for a Military Tribunal. This change of plans leads them to a familiar cabin to search for evidence for the trial, but ultimately, they are left with more questions than answers. While at the cabin, a plea comes from Rebel troops situated on the St. Johns River to put out the light in the St. Johns River Lighthouse. The journey from the cabin to the lighthouse and then to the trial is filled with new experiences and unexpected challenges. There are uncertainties on the river, encounters with Yankee troops, a kidnapping uncovered, the Military Tribunal, meeting the governor, and more...as they faithfully trust God to uphold them " with His righteous right hand ".
