In Los Angeles, the Vista Pacific Flight 7000 departs to Tokyo in a ten-hour flight. The flight attendants Laura Baxter and Suzy Lee receive the passengers, among them Brad and his wife Pia Martin that have broken up; the newlywed Rick and Liz Lewis that are traveling in a honeymoon trip; and the well-resolved Jacinta Bloch, who is sat close to Liz and Rick.
Laura is having a love affair with the Captain Pete Haining that is married and her behavior is questioned by Suzy. After passing by a turbulence, the passenger Lance Morrell dies and the crew brings his body to the first class. Then there is a pressure drop in the cabin and Brad helps several passengers how to use the oxygen mask. When the pressure returns to normal, Captain Haining loses contact with ground control.
Soon weird things happen in the plane and Brad, Rick, Jacinta, Pia and Liz decide to investigate who Lace was. Soon they find that he was a dealer of dolls and a "shinigami" inside a wooden box. Jacinta explains that the Eastern doll would be equivalent to The Ripper; however she collects souls only if those that let go whatever hold them to Earth.
