Jade steals an innovative medicinal elixir from her sister to claim first place at a prestigious pharmaceutical trial, only to discover the victor must wed the terrifying, cursed sovereign of the serpent domain. Panicked by the gruesome prospect, Jade runs to her sister's fiancé for salvation. Betraying his lifelong promises, the cowardly fiancé agrees to marry Jade, leaving their biased parents to shove the innocent sister into the serpent clan's bridal carriage instead.
Expecting torment and demise, the cast-aside bride discovers the serpent sovereign is an honorable, breathtakingly powerful warlord whose curse yields to her rare alchemical mastery. When Jade's fraudulent potion recipe collapses and the traitorous family arrives begging for aid, the serpent monarch fiercely shields his new consort, casting the miserable hypocrites into ruin.
