We open the episode within the Ghost Zone, where we see a female ghost, with a surprisingly uncanny resemblance to Vlad Plasmius. She is currently gloating about having pilfered an ancient Ghost Zone artifact, with which she intends to use for obviously nefarious purposes. But just then, she is attacked by the Fenton Spectre Speeder, being driven by three young children. The tallest of them jumps out and does an amazing trick, HE GOES GHOST! His ghostly appearance is somewhat inverted from Danny's, but a striking resemblance can be seen. This boy then does battle with the evil ghost woman, (who the boy even refers to as Plasmius). But when she proves too fast and strong to handle alone, the girl of the three also joins the fray, while the youngest of them drives the speeder. She also GOES GHOST, except this girl however bears a striking resemblance to Sam. The 2 ghost children battle the female Plasmius and eventually retrieve the artifact she stole, much to her infuriation. The three children return to the human world and reveal themselves as the children of Danny Fenton/ Danny Phantom. We then hear a voice over of all three of the ghost hybrids, as they begin to recall how they got to this point in their lives.
It's been 15 years after the "Disasteroid Evasion" and Danny is no longer hunted by humanity, he's praised as a hero throughout the world and he has even settled down with Sam. This has led to the two of them having three children; Jack (their first born), Lilith (the middle child) and David (the youngest). Danny has since continued his obligation as a Ghostly hero and protector Amity Park and the Ghost Zone. As to his family, all seems wel1. Sam has become a bit more calm and collective over the years and their children are all a sweet bunch, but also pretty different. Jack is a bright lad, but a bit of a troublemaker, Lilith (or Lily as she's been nicknamed) is a sweet and honest little girl, but a bit of a perfectionist. Their younger brother David is a shy but highly intelligent boy.
But one thing about them has remained the same, despite the fact that their father is an Artificial Half-Ghost Hybrid, the Fenton three (as they are often referred to as) have yet to show any signs of being part ghost. Though Jack displays some ghost traits ("Snow White Hair and Glowing Green Eyes"), neither he or his little siblings can do anything their father can. Though Sam and Danny are actually happy of this, the last thing they wanted was for their children to be involved in the dangerous world of the Paranormal. Unfortunately it's because of this, that Jack and David are often picked on by Don Baxter (Dash's son), while Lily is tormented by Helena Baxter (Paulina's daughter). The Fenton Three have been called "No-Ghosts", "Ecto rejectos" and "Paranormal dweebs" (which weren't particularly good nicknames, but they stung all the same).
Though some people at their school; Casper Elementary, are actually very nice to them, particularly a 6th grader named Eliza (whom Jack has a crush on). But unfortunately, that doesn't completely make their pain and outcast feeling go away. But lately, Jack has been having strange feelings, ones he can't truly explain. Lily has been feeling a similar way, but David has been feeling just fine. And being of such sound condition, David suggests that his brother and sister go see their Aunt Jazz.
They go to see their Aunt and she feels that these are all signs of them having ghost powers. Naturally, Jack and Lily highly doubt that, but David feels that it's actually very plausible. Their father only got his ghost powers quickly because they were artificially introduced to his system. But the three of them have theirs within their genes through blood line, so it's possible that their ghost abilities have been dormant inside them and are just now starting to manifest themselves (David was always the smartest of the three).
Although, that doesn't explain why his aren't revealing themselves, but that is a question for another time. Jazz decides that this warrants more investigation, so they pay a visit to the lab of Grandma and Grandpa Fenton. They were out at the moment, so Jazz and the kids use some of their ghost scanning equipment themselves (fortunately, after finding out their son was half-ghost, Jack and Maddie have patented some of their lab equipment to be safe for examination subjects).
After a few tests, they all prove to be positive for Jack and Lily; they prove that traces of ghost DNA are indeed within their Genetic structure. But they all prove negative for David; they prove that his DNA is that of a regular human. Though disappointed, David does not let that distract him from the main focus, his big brother and sister. When the computers show that the Ghost portion of their DNA is expanding irregularly, David is given the impression that 2 possibilities are inevitable, either Jack and Lily will be able to transform at will like their father or the Ghost Gene will continue to grow until it has overwhelmed their systems.
Jazz suggests that they tell Danny and Sam right away and David agrees. But Jack and Lily are afraid that if their parents find out about this, they'll do something to take away their powers. David is quick to point out that, considering there's a chance that their lives are at stake that would probably be a good thing.
But even still Jack and Lily both agree that they don't want to remove the very things that make them special. Jazz tries to console them by telling them that's not true, but to no avail. Nevertheless, Jazz highly suggests they speak with their parents immediately, given the circumstances. Reluctantly, they both agree that their aunt his right. So they head back to Danny's penthouse (bought for him as a gift for saving all of Australia from a generic Koala Ghost). Only to discover that it was in complete shambles and both Danny and Sam are gone. The only thing they find in this mess is a card, a card with a purple, stylized V. The flashback ends for now, when the Fenton three hear their mother calling them for dinner.
