Danny goes to his father in the Fenton lab before school, eyeing Jack and his newest invention - the Fenton Ghost Fisher. Jack has to leave for a moment to use the restroom so he plants the fisher on Danny to hold until his return. It snags a ghost which Danny reels in to reveal a dragon ghost. He goes on the defensive and fights the dragon until her amulet comes off, ending up inside Danny's backpack—unbeknownst to both. The dragon reverts to a ghost girl from Medieval times who only desires to go to the princess costume ball, leaving Danny completely baffled upon her exit.
Later at school, news is already underway throughout the student body about the upcoming school dance. Both Danny and Tucker are excited despite their lack of dates, while Sam proceeds to display her utter displeasure towards both the dance and being asked out. She is interrupted (and irritated) when Danny and Tucker eye the class beauty, Paulina. With a push from Tucker, Danny awkwardly tries to ask her to the dance, but his nervous behavior triggers his ghost powers, causing his pants to fall. Paulina and the entire student body laugh at him, the former making a quip towards him until Sam confronts her. She fights back by calling her shallow, a word Paulina takes offense to. As an act of revenge, she vows to take Danny away from Sam.
Paulina confronts Danny at his locker later on until Dash interrupts and shoves him into it to flirt with her. An invisible and angry Danny sneaks behind Dash only to discover his power of possessing people. He overshadows Dash and embarrasses him in front of Paulina. A dazed Dash walks off afterwards while Paulina frees Danny from his locker, the amulet from earlier dropping out of his backpack as he falls. Paulina immediately sees it and with a fib from Danny that he got it for her, she agrees to go to the dance with him. As she walks away, her eyes (as well as the amulet) glow. Danny's pants fall down once again, which gets him in trouble with Mr. Lancer, now wanting to discuss this matter with his parents. Too afraid to confront his currently frustrated father (when his Fenton fisher has yet to snag a ghost), Danny overshadows him and takes him to the conference where he is let off easily by flattering Lancer. Enjoying his style, Lancer insists on him chaperoning the school dance.
Danny, Sam, and Tucker are at the same mall as Paulina who's currently shopping for a shirt, still donning the amulet. Admiring a limited-edition shirt but then finding out that there's nothing left in her size, she becomes furious, unleashing the amulet's power and the dragon within. Danny fights the dragon, enough to revert Paulina back to her normal self causing her to not remember her events as a dragon (but acquiring the shirt she desired). Shortly afterwards, Tucker gets himself a date with Valerie Gray when her previous partner, Kwan, asked someone else.
The trio research the amulet on the Internet before the dance, learning that extreme distress or anger causes the wearer of the amulet to trigger its power and transform them into a dragon. Danny immediately recognizes the amulet as the one he gave to Paulina (prior to that, he assumed the necklace belonged to either his mother or sister) and so forth has the mission of getting it back from her. Sam once again displays her hatred for the dance to which Danny concludes she secretly desires to go so by possessing Tucker, he gets her to go as his date saying Valerie stood him up to which Sam eagerly agrees.
Danny goes with Paulina, trying to get back the amulet and deal with his father whom he has to constantly overshadow during the dance. There, Danny lies about the amulet by saying it belongs to Sam, angering Paulina. A panicking Danny quickly tells Tucker to keep an eye on his father while Sam tries to find Paulina. She catches her in the restroom and apologizes for calling her shallow. Learning that Sam is just Danny's friend and not girlfriend as she previously assumed, Paulina gives the amulet back to Sam (by placing it around her neck) and confesses how she played with his heart to get back at Sam and is now going to dump him. Sam gets furious at Paulina for using Danny, which instantly turns her into the dragon, and kidnaps Paulina who faints upon seeing her.
Discovering the dragon, Danny fights it off (later discovering it to be Sam) and manages to capture her with the Fenton Fisher, tying her up and pulling the amulet off. With the date gone bust, Sam asks Danny for one last dance and he accepts stating that he'd love to. While Danny and Sam slow dance, as seen in the picture on the right, Tucker complains about his lack of a date again. The ghost girl (Dora) then appears and still wishes to go to the ball, causing Tucker to decide he's in no hurry for a date and wants to cut into the middle of Sam and Danny's dance.
