The first incident Laura details in the novella is in her childhood: Six-year-old Laura tries to sleep when she is visited by a mysterious woman. (Later revealed to be the Vampire Carmilla, or at least represented Carmilla) who bit her in her chest. Then the narrative moved forward thirteen years. Laura's father received a letter from his friend General Spielsdorf, in which the general revealed Ward Bertha had died. The general hinted that some kind of monster had killed Bertha.
Later that day, the chariot carrying Carmilla and her mother crashes near Laura's castle, and her mother convinces Laura's father to take care of Carmilla for a few months. She has an important business. Laura was excited to have Carmilla visit, and the two soon became fascinated with each other. Shortly after Carmilla arrives at the castle, a local farmer girl finds her body and rumors of a vampire sneaking around in the area.

Then Laura had a strange illness and languished for several months. Laura wakes up one night from a nightmare to meet Carmilla at her bedside. But Carmilla escaped from the room. Laura found Carmilla's room locked but Carmilla was not inside. Laura's father decides that Carmilla sleepwalks and finds a way out of the closed room. The doctor was sent to the doctor and was very worried about Laura's health. Laura's father took her to the village of Karnstein in search of a priest. Along the way, they meet with a general who tells them about Bertha's death. Bertha's story is like Laura, she is fascinated by a young woman who is a guest and begins to have chaotic dreams. The general is on a mission to avenge her death, and as such he recruited vampire expert Baron Wardenberg to help him.
