Twelve-year-old Seth wants to prove to his stepfather, the game warden, that he is responsible enough to use his shotgun on his own. Without permission, he takes matters into his own hands and shoots his first rabbit. He is worried about what his father will say when he finds out—and Seth himself is unsure of how he feels about it—but before he can confess, Seth's life is turned upside down.

In the woods near his house, he sees poachers slaughter a moose cow and injure her calf. Rather than tell his stepfather about the incident, Seth tries to save the calf, but the poachers know who he is and threaten his family. Can he rescue the moose and bring the poachers to justice? He has to try.
