SYNOPSIS: Abby, a young lighthouse keeper, is alone tending her duties when a fierce, unexpected spring storm begins. She is surprised by two men, Mr. Trent and Jack. They are "Moon Cussers." They want two ships, scheduled to return that evening, to wreck so they can lay claim to the goods that wash ashore. Mr. Trent is desperate. He has a dying wife and three children and will do whatever is necessary to accomplish the task. Jack is more ambivalent and less ruthless. As the evening progresses, Abby is determined to light the lantern for the safety of the men on the ships. Mr. Trent is equally determined to stop her. That leaves Jack caught in the middle.
