A bizarre time travel incident forces an 18-year-old girl to take over the mess left by her 28-year-old "drama queen" self: a husband, the Richest Man, who hates her to the bone; a biological son she has neglected; and a fate that dooms her to a "tragic death on the streets." To survive, she must make her husband give up the idea of divorce within one month. So, she fights off scheming rivals and crushes a Kept Man, while using her "youthful version" to win back her husband's heart.
