"Abandoned, frightened, and completely unaware of his own identity, the monster wanders through the wilderness searching for someone who would understand and shelter him.
He finds brief solace by hiding out in the woodshed of a remote cottage inhabited by a family of peasants. While they are unaware of his existence, he learns every part of their lives by eavesdropping on their conversations and comes to think of them as his own family, calling them his 'protectors'.
One day, the creature musters the courage to finally make his presence known. He introduces himself to the family's patriarch, their blind father, and experiences kindness and acceptance for the first (and last) time. The blind man can not see his "accursed ugliness" and so treats him as a friend. When the rest of the family returns, they are terrified of the creature and drive him away. Bewildered but still hopeful, he rescues a peasant girl from a river, but is shot in the shoulder by a man who claims her.
Heartbroken, the creature renounces all of humankind and swears revenge on his creator, Frankenstein, for bringing him into the world.
The monster searches for Frankenstein relentlessly, guided by some papers which were in the pocket of the clothing he took from his creator's rooms. From these he discovers Frankenstein's whereabouts, but also discovers the horrific details of his own birth. Upon arriving near Frankenstein's village, he meets and tries to befriend a small boy hoping that the innocent youth will not be prejudiced against him. The boy is instantly frightened and threatens to call for his father, Monsieur Frankenstein, revealing to the creature that the boy is related to his enemy. The creature kills him.
Full of grief and despair, Frankenstein retreats to the mountains to find peace within himself. The monster approaches Frankenstein on top of the mountain and insists that Frankenstein hear his plight. Here the monster tells Frankenstein his story and pleads with him to create a female equivalent to himself so that he can hide from humanity with one of his own kind. Frankenstein agrees, but relents just before finishing the mate, aghast at the possibility of creating a race of monsters. Enraged, the creature swears he will destroy everything Frankenstein holds dear. The creature's final words before fleeing are "I will be with you on your wedding night!".
He later fulfills his promise by killing Frankenstein's best friend and his bride. Frankenstein's father then dies of grief. With nothing left to live for, Frankenstein dedicates his life to hunting his creation down and destroying him. The search ends in the Arctic Circle when Frankenstein loses control of his dogsled and falls into ice-cold water, contracting severe pneumonia. He is rescued by a ship exploring the region and relates the entire story to its captain before succumbing to his illness and dying. The creature later boards the ship, intent on taking his final revenge, but is overcome with grief upon finding Frankenstein dead, having lost the only family he has ever known. He pledges to travel to "the Northernmost extremity of the globe" and there burn his body to ashes, so that no man can ever create another like him. He leaps from the boat and is never seen again."
