Determined to return to the modern world, Qu Tan’er repeatedly tests an ancient jade bed believed to possess the power to transport her through time, leading to one hilarious mishap after another.
As they spend more time together, Qu Tan’er and Mo Liancheng gradually fall in love. Side by side, they thwart the schemes of the Crown Prince, her elder legitimate sister, and their other enemies.
In the end, Qu Tan’er chooses to remain in the past and spends the rest of her life with Mo Liancheng after he ascends the throne.
