When the heat repeatedly goes out in Melinda's house and antique shop, she starts getting strange visits from the spirits of an airline pilot and flight attendant who complain of being cold. Initially Melinda has trouble understanding the messages they are trying to communicate, but she eventually figures out that they are trying to warn her about a jetliner that has lost cabin pressure and is going to crash.
