Athena is tasked with safely delivering a prisoner to testify on a high-profile case. Meanwhile, a light plane is hit by a swarm of bees and sent careening into a passenger plane.

Athena's only chance of surviving and saving everyone on the flight is to attempt to land the plane before it crashes and call on the 118 for help.

Following Maddie’s mysterious 9-1-1 call, Chimney returns home to find his daughter alone and Maddie nowhere to be found. He then enlists Athena and Romero to help investigate.
