Ace hates sharing a computer with his older sister, Nora. When Ace and Nora get into a fight over the computer, they're both grounded from using it. But Ace has a new idea he wants to work on—designing a magician character named Fabian who reminds him of learning magic tricks with his absent father. Ace sneaks onto his mom's top-secret work computer in the middle of the night. But when Ace saves the Fabian file, something strange happens. Fabian comes to life on the screen and starts deleting files. When Ace and Nora try to fix the issue, they're sucked into the computer world. Now the siblings have no choice but to work together before Fabian erases everything on the hard drive—including them.
