Outside of the sheriff's office, a man stands in awe of a bounty on the office's wall. He reads the bounty and it states that the Nebraska Family (from the previous episode) is wanted for $$700,000. The sheriff leaves his office and informs the man that the Family has been caught already, by the entire city of Inepril. The man is disbelieving of such news. (It seems Vash gave the entire city his bounty so that they could rebuild their power plant.)
In Inepril City, Vash is being paraded around town by Meryl and Milly. Meryl is loudly proclaiming how great Vash is and how everyone should fear him. Suddenly, a huge sand steamer (a monstrous locomotive) rolls into town. The steamer has tons of engineers inside and merchants and a very beautiful lady who everyone in the town makes eyes toward.
Sunset approaches and Vash is standing alone on a ledge near the power plant. From behind, the gorgeous lady we saw earlier (named Elizabeth) arrives and begins recounting some portions of Vash's life. Vash takes one look at the lady and immediately wants to marry her. Elizabeth tells Vash that she is a high-ranked engineer and that she wants Vash to do a favor for her. In exchange, Elizabeth will give Vash "whatever he wants." Vash immediately agrees though he does not notice that he and the woman are being watched by some half-man, half-robot that looks to be quite menacing.
Meryl and Milly are wandering around outside, near the sand steamer. Vash enters the scene with Elizabeth (being her new bodyguard). He acts incredible submissive to her, allowing her to call him "Spot" and calling her "master." Meryl gets noticeably upset (jealousy?) and leaves.
Elizabeth takes Vash to the hotel she's staying in. She tells Vash to sleep in a different room than her. The moment Vash enters the room, he is attacked by the cyborg. After a quick battle, the cyborg drops a bomb inside the room and flies outside. The room explodes and Vash is sent tumbling to the ground outside. Elizabeth opens her window and thanks Vash, she had put him in the room where she was intended to stay.
The next day, inside the plant, Elizabeth is working diligently with Vash at her side. Meryl and Milly storm in and yell at Vash for the damages he caused (their insurance company has to pay for all damages caused by Vash after all). Before anything can be resolved though, there is a major system error, it seems one of the sectors of the plant has malfunctioned. Vash and Meryl run toward the sector.
Once inside the sector, the cyborg reveals himself and Vash pushes Elizabeth away to battle him. It only takes a little while for Vash to defeat the cyborg. But was that his real enemy?
Elizabeth leaves the room and closes the door behind her. It seems she was the one who hired the cyborg in the first place. She reveals that Vash destroyed her city when she was a little girl and made the entire population homeless and at war with each other. Elizabeth's parents even died in this fray.
Vash looks on sadly as energy beams fill the room. Elizabeth tells everyone in the plant to evacuate - that everything will soon explode.
Mysteriously, Vash steps to the middle of the room and lifts his hands high into the air. The plant doesn't explode. Vash leaves the plant a few moments later and everyone cheers heartily.
Elizabeth approaches Vash and pulls a gun to his stomach. Vash tells her that he has no memory of anything from his earlier days. Elizabeth, after some hesitation and after hearing how much the city loves Vash, decides finally not to shoot him. She simply falls to the ground in tears. Vash also sheds tears and hugs her in empathy.
