The plane crashes, everyone dies, and the captain's spirit seeks help

In the church, a couple - Melinda and Jim - are getting married. Suddenly, there's no one in sight who asks Melinda for help. It turns out that Melinda grew up like her grandmother, with a mysterious ability to communicate with ghosts, and her grandmother told her that these ghosts refuse to leave because there is unfinished business between them and the living, and called them "land ghosts". Because Melinda has this special ability to communicate with ghosts, she is often approached by ghosts to help her and conduct some paranormal investigations. Because of this, Melinda is often criticized and questioned by people, but when she discovers that she can help not only the dead, but also the living, she knows that her special ability is not a burden but an asset!
