The story revolves around Victor, an ordinary man entrusted with an extraordinary mission that will challenge all aspects of his life.

Victor works as an OFW to look for his mother Vivienne (Connie Reyes). He becomes friends with Magnus (Miguel Faustmann), the curator of the museum where he works. Magnus' life is jeopardized because of Loki (John Estrada). Victor finds out that Magnus is not a mortal being: he is the god Magni, one of Thor's sons. Before Magnus dies, he gives Victor a magical compass that leads him to a mysterious mountain. Victory finds an iron gauntlet that lets him use the Mjolnir, the powerful hammer of Thor (Conan Stevens). Victor returns to the Philippines and becomes the Hammerman, his town's courageous superhero. In his adventures, he battles monsters and forms alliances with Norse gods to protect the people he loves from Loki's schemes.
