While enjoying their holiday away from Moya, Crichton, D'Argo, Jool and Chiana get a little too drunk. The next day when Crichton and D'Argo come to they find that Chiana and Jool are nowhere to be seen, now Crichton and D'Argo must work out what really happened the night before.

With his wormhole research stalling and his situation desperate, Scorpius inserts the original 'neurochip' into his own brain. He hopes to make contact with the clone of Crichton's personality that spilled in to the chip when it was in Crichton's brain. When they meet, Scorpius realizes that it's not going to be easy to get the clone to share information. Meanwhile, a defecting Peacekeeper scientist offers Crichton the secret of wormhole technology.
