Because of a mix-up on his wedding day, the 200-pound Peter Ortiz mistakenly enters CEO Olive Knox's car and is forced into a disastrous encounter that leaves Olive injured. Furious, she exiles Peter to the countryside and plans to divorce him after five years. But Peter's sibling, Riley Ortiz, plots to kill him for marrying into wealth. At the critical moment, the soul of an ancient divine physician—also named Peter—crosses into his body, defeats the killers, and begins thriving as a village doctor. One month later, Olive discovers she's pregnant… with quintuplets.
