Shell is resigned, but Leonard is determined to fight. Shell prepares to make a weekend journey to find the legendary Hornet Spooklight, a supernatural haunt of the Ozarks. The Cherokee Indians removed to Oklahoma on the Trail of Tears are aware of the tragedy that belies the mysterious light, and refuse to go anywhere near. But Shell's infatuation with the legend draws from a spiritual inheritance she does not yet fully grasp, and she decides the time has come to seek out its enigmatic source.

When they finally discover the iniquitous light, the fiery conclusion propels them to a catastrophic fate.
