Insurance adjuster Kael marries the mysterious Sera in a whirlwind wedding. After marriage, his coworker Mallory keeps warning Kael that Sera is a serpent witch who feeds on human life force, fabricating evidence to fuel his doubt. At Moonfall Manor, the arrival of his best friend Isolde and snake hunter Casper pushes Kael to fully believe his wife is an inhuman monster.
Then Sera unveils the truth. Mallory seeks revenge for a broken engagement, while Isolde envies her bloodline. The two conspire together to frame her. Sera is the sole heir of the Morrow family, who built a magic temple five hundred years ago. Kael wakes up to the plot, rebuilds trust with Sera, and they stand side by side to confront the remaining schemes.
