Two travelers are shipwrecked and a doll runs away from home.

Laszlo and Colin take a three-hour cruise to find Plum Island, and Colin's possible origins. However, their cruise is interrupted by the voice of a beguiling siren. Meanwhile, Nadja Doll grows upset that everyone is ignoring her and runs away.—Gislef

At Mariners Harbor on Staten Island, Laszlo and Colin pick a ship. Laszlo turns into a bat and flies onto it, and kills some of the passengers while the others run. Colin goes on board and helps Laszlo toss the corpses overboard, and they prepare to cast off.

Nadja and Nandor Skype with Scott Bakula, who has no idea why they wanted his help. The vampires finally realize that he's not "Count Bakula" and thus not a vampire. Scott manages to sign off.

Nadja and Nandor tell the crew that they have worked out how they're going to share power by ruling on alternate days. The Guide tells the crew that it's a terrible solution, because one of them spends their day undoing what the other one did the previous day. She complains that it's the most poorly run Vampiric Council since Paduk the Deranged, who shared power with what he thought was a talking footstool. Nandor and Nadja figures that it's a win/win.

Nadja finds out what Nandor is doing and goes to confront him, with the Guide in tow. They both ignore Little Nadja, and when they find Nandor he explains that he's set up a Vampiric Council-sponsored Fun Run for MS. Nandor figures that it's a good idea because it makes humans healthier, so they have better eating choices. Little Nadja comes in and tries to get Nadja's attention, and Nadja ignores the doll and points out the problem that it will reveal vampires to the world. She says that she's going to undo it when she's in charge and walks off.

Nadja Doll complains to Guillermo and the crew that it feels like she's become invisible to everyone. Guillermo isn't thrilled to be teamed up with the "b-team", and goes to do his chores. Little Nadja tells the crew that Guillermo is a chore.

Laszlo and Colin tell the crew that they're heading to Plum Island, and Colin thinks it holds the secret to his energy vampire origin. It's a government-owned animal-disease research center. Laszlo boosts of his previous life as a sailor.

Nadja Doll tells the crew that her life has been difficult. She's been singing, dancing, and fencing with the residents. However, Nadja Doll believes that she doesn't fit in and hits the road. She loudly tells the others that she's leaving, but they're too busy arguing to notice and Nadja Doll leaves.

Colin smears sunscreen on his chest, and he and Laszlo hear a woman singing. They start to hear to the song, but then figure it's a trap when the woman stops singing. When she starts again, they figure it's not a trap and keep sailing.

Nadja discovers that Nadja Doll has left, and that she's trying to create a big scene. Nandor figures the doll will come back, but Nadja wants to go find Nadja Doll. She changes back and forth between wanting the doll back and not wanting it.

Nandor goes to find Guillermo to help, and finds him in his room with the Guide flirting with him. Nadja tells Guillermo to stay and search the attic, but Nandor doesn't want to be alone with Nadja who is having an argument with a fragment of herself. The Guide wants to wait in Guillermo's bed, and he tells her to get out of his room. She doesn't.

Laszlo and Colin go ashore and find the siren bird-woman, Sheila. She tells them not to interrupt her song or join in, and the vampires find Sheila hideous and start to leave. Sheila eats a dead fish, and Laszlo realizes that Sheila is a siren. She suggests one of her "suitors" might want to complete for a trinket. Laszlo turns into a bat and flies off, disgusted, but then comes back when Sheila sings again.

Nandor, Nanja, and Guillermo go to a local department store to search for Nadja Doll. Nadja figures that Nadja Doll is on a shelf, and waiting for a little girl to come and buy her. As they search, Nadja Doll leaps out at Nandor and attacks him. Nandor finally throws her off, and Nadja's spirit jumps into a nearby mannequin. They go after it, making a mess, while part of Nadja's human spirits remains in Nadja Doll.

Sheila wraps some ropes up around Laszlo and Colin, without making any knots, and searches the boat. Laszlo refuses to leave Colin, and they finally realize that they're being enchanted. Despite that, they both admire Sheila. Laszlo changes into a bat and flies off, and Sheila is thrilled to be alone with Colin.

Nandor, Guillermo, and Nadja go outside to continue their search, and Nadja admits that she didn't give Nadja Doll a name. They discover that Nadja's human spirit has possessed a statue, and it refuses to go back with them because it figures they don't love her anymore. The spirit leaves the statue and flies off, and Nadja says that she's had enough. The spirit possesses a nearby mouse inflatable and runs off, and Laszlo arrives and tells Guillermo that he needs him to make a device impervious to external sounds. Meanwhile Nandor and Nadja go off after Nadja Doll.

Guillermo takes Laszlo to Best Buys to look for noise-canceling headphones. The clerk asks if they need help, and shows them a drone. Laszlo is intrigued by Sen surround, and the clerk Judi flatters him while Guillermo shops. Laszlo hypnotizes the cashier, Kevin, so he doesn't have to pay or buy a warranty. He agrees to gives the cashier his email, though. Guillermo and Laszlo leave with lots of electronics, and Laszlo realizes that he's forgotten all about Colin because Judi enchanted him. He turns into a bat and flies back to Plum Island.

Colin and Sheila sing together. When they're done, Colin says that maybe life is an ocean rather than a highway. Sheila figures that Colin is an odd one, and Colin tells Sheila that he likes her. Laszlo returns and tells Sheila to release Colin. Colin talks to Laszlo privately and says that he's in love with Sheila, even when she's not singing. Laszlo figures that Colin is mad.

Nandor and Nadja catch up to the mouse statue, and Baby Doll tearfully says that they don't want her. Nadja insists that they do, while Nandor accidentally punctures in the inflatable. As the inflatable deflates, Nadja Doll tells Nadja that it would be easier if they left it. Nadja talks about how she's been busy trying to get the others to take her seriously. She tells Nadja Doll that she's going to do better for her, and for herself, and invites the spirit to go back into the doll and come back and live with them. The spirit does so and agrees, and Nadja tells Nandor that she's taking the next day off.

Laszlo tells Colin that Colin isn't in love but enchanted. Colin isn't convinced and goes back to Sheila, and Laszlo puts on a pair of the sound suppressors, has the crew cut their mics, and puts a suppressor on Colin. Laszlo flies off with Colin, and Sheila cries and then looks over at the crew.

At the residence, Nadja assures Nadja Doll that she looks all right. Nadja has realized that she's neglected Nadja Doll, and the silly sweet part of her own personality. Nadja Doll has realized she needs to communicate her emotional needs to everyone, and to herself.

Laszlo checks in on Colin and apologizes for not getting to Plum Island. He asks if Sheila's spell has worn off, and Colin says that he isn't sure and if felt like true love even if he didn't experience it for real. Laszlo tells him that Colin didn't experience true love and leaves. Colin takes out a hidden radio and listens to Sheila singing.
