Ben and his nephew Franklin are in a video arcade playing games, and Franklin is just whupping Ben every which way. Heading back to the Baxter Building, the two meet up with a scientist who's invented a video game and has come to see Reed about it. Ben, hoping for some pointers on how to keep up with Franklin, invites him up.

The game, Space Saver, is pretty obviously a PacMan rip-off, but when Ben sets it up and starts playing, the three of them are suddenly teleported to the planet K'rith. It turns out that the planet is under attack by some Gobblers from the planet Gh'runji. The K'rithians had intercepted the computer code from the game, thought it was real, and decided to transport the hero, Space Saver, to save them. Instead, they got Ben, Franklin, and the scientist, who have to save the day...
