Lisa Henrietta Reisert works at the Lux Atlantic in Miami. She is just returning home after her grandmother's funeral when she meets a charming man named Jackson Rippner (who never goes by Jack ) at the airport. What seems to be love at first sight, soon turns into something deadly. As soon as the plane goes into the air, Jackson (who happens to have gotten a seat next to Lisa) tells her of his sinister plan which he needs her help for. She must co-operate in his plan or her father will be killed. Flight 29 will be boarding at 5am, but Lisa may not.
