After dying in a car accident, Sophia is miraculously reborn as an eighteen-year-old transfer student. She discovers that her son, Leo, has become a school bully, while her daughter, Melody, is being abused by their malicious guardian, Chloe, and Chloe's daughter; meanwhile, the family's massive trust fund is on the verge of being stolen. Approaching her children as a peer and joining forces with her husband, Ethan—who has also been reborn—Sophia unravels the truth behind the conspiracy to murder her and seize the fortune, orchestrated by her foster brother, Arthur. Ultimately, they reclaim the fund and bring the true culprits to justice, reuniting as a family and finding happiness that transcends the boundaries of life, death, and time.
