Reg Park stars in this campy double feature as Hercules, a man of incredible and mythical strength who faces the task of battling enemies from the netherworld -- namely the undead and the ghostly -- who seem intent on harming Hercules' son no matter the cost. But while Hercules is away, a coup d'état of sorts takes place as his nemesis, Gia, makes it her mission to ensconce her own son in the power seat. Will she succeed?
