Lisa been trying to get certified as a pilot. But an incident shatters her confidence. A woman who knows the girls gives them a cheesecake but she doesn't know that some the ingredients were bad. The girls give the cake to the pilots who eat it and come down with food poisoning. The Captain puts the plane on autopilot and tells the girls to wake him up when they're about to land. Marcy asks a doctor who's among the passengers if he could help. And what he does is give them a sedative which knocks them out. So Pam and Marcy tell Lisa that she has to land the plane. So they call the tower who brings a pilot to tell her what to do.
