A plane loadmaster for the military named Davis is woken up from a nightmare of being crushed beneath his own cargo to go on a med-evac mission in the South American jungle. When he gets on the plane, he finds out that it is now a recovery mission for dead bodies. They arrive at their destination and load over a hundred coffins onto the plane along with two living people, a nurse Davis knows named Pembry and a traumatized young medical officer named Hernandez.  As they take off, Pembry tells Davis that Hernandez was one of the first responders on the scene of a mass suicide in Jonestown in which a thousand people drank poison, including feeding it to their children, whose bodies are now on the plane. Hernandez says he hears children singing on the plane. Davis goes to investigate but doesn’t see or hear anything, and returns to his bunk. A few minutes later, he hears a scream, and both Pembry and Hernandez tell him that they heard children playing. When he goes to check again, Davis hears it too. He gets another officer to come with him and they both listen to the sounds of the children until they hear something hitting the inside of one of the coffins. They open the coffin and see the children's bodies, and a fly comes out and disappears into the cargo hold. Sickened, the two officers close the coffin and no longer hear any noise. A funeral service unloads the coffins when they land, and within a week Davis is on another mission flying cargo.
