It's night. The Skipper comes sleepwalking out of his hut. He's acting like he's back in World War II. His yelling wakes up Gilligan who follows him. Skipper is trying to convert a radio into a transmitter. But when Skipper yells about the dive bombers Gilligan jumps into the lagoon. Then the Skipper heads back to the hut. Gilligan wakes the Skipper up by dripping on him. Gilligan explains that the Skipper was sleepwalking but he doesn't believe it, insisting that he was in the hammock all night. He even suggests that Gilligan was really sleepwalking.
Sipper and Professor are listening to the radio when they hear about Alice McNeil flying around the world. According to the Skipper's calculations she's going to be flying right over the island. He suggests building a big signal fire to catch the plane's attention but is concerned about cloud cover blocking the view of the fire. Gilligan mentions the Skipper's sleepwalking episode where he turned the radio into a transmitter. Skipper suddenly remembers and admitts to Gilligan it was his dream after all.
Skipper tries to go to sleep but Professor and Gilligan are staring at him. Gilligan stands guard to make sure that no one bothers the Skipper. Ginger and Mary Ann are singing a lullaby. The Skipper is almost asleep until Gilligan joins in the singing.
Professor is listening to the radio trying to figure out where Alice McNeal is. Skipper just won't fall asleep. Gilligan asks Thurston for some tranquilizers for the Skipper. He puts a couple of pills into the Skipper's mango juice. Then Mary Ann, ginger, and the Professor each put two pills into the juice. While sitting at dinner Skipper won't drink his mango juice. Instead he finds the pills and takes two washing the pills down with mango juice thinking that they will help him go to sleep. Now it's waiting time.
Professor hears on the radio that Alice McNeal is an hour ahead of schedule. She also wants to talk with anyone who can receive her signal. Skipper comes sleepwalking out of the hut. Professor and Gilligan follow him back to the lagoon. Gilligan falls into the water. When he spits out the water in his mouth Skipper wakes up.
Professor hynotizes the Skipper and uses the rest of the castaways as actors in his dream. Professor writes down everything the Skipper says in hopes he will get the iformation he needs to turn the radio into a transmitter. Afterwards Skipper, Professor, and Gilligan try to see if the transmitter works but it's doesn't. Gilligan fiddles with the transmitter while on guard duty. He actually talks with Alice McNeal.

The plans flies overhead and Alice says thanks for the chat over the radio.
