In Norse Mythology, during Ragnarok--the final destruction of the world--many gods failed to survive, including Thor (Conan Stevens). Before Thor's death, he orders his son Magni (Miguel Faustmann) to hide his weapon, the hammer which they call as the "Mjölnir." Magni then goes to the world of mortals to wait for the new rightful owner of it. Later on he meets Victor Magtanggol (Alden Richards), who is said to be the chosen one in taking care of the Mjölnir so he could protect the world and his loved ones from Modi (Pancho Magno), who is upset for not inheriting the weapon, and Loki (John Estrada), who has desires to spread chaos in the mortal world.
