At the werewolf academy’s harsh summer trial, Selene is already fighting a fatal blood clotting disorder when Kane, her Alpha boyfriend, cages her in a sealed punishment box under the scorching heat. Vivian’s jealousy pushes the cruelty further: she drugs Selene’s water and makes it look like Selene is faking her illness, while Kane throws away the only key. Trapped inside, Selene dies. When the surveillance footage and autopsy expose the truth, the two conspirators are brought to complete ruin, and Selene’s soul finally rests in a bright sunflower field.
