Matt, the father of Cleo and Alex, accidentally disappears into a cyberworld. Later, Alex also disappears into a cyberworld just by touching the computer screen. Cleo sees him disappear and even sees everything going on in the mythical world he went to. Alex does come back, and they realize what must have happened to their father. Cleo and Alex decide they are going to have to go back to find their father.

Alex decides to go back into the mythical world in the hope of finding his father. This time he knew touching an object on the screen would take him there. By touching a different object, he goes to a different cyberworld. This time he ends up in a world of Gods. He makes it back... but didn't find his father, yet. They will have to try again next week. In the meantime, their father is no longer being looked for as a missing person, but as a possible criminal. It was discovered that something disappeared from inside a statue. Some think he took whatever it is and fled. Only Cleo and Alex know what happened. Should they tell someone?

Alex has plans to go back to another mythical world in the hopes of finding his father, but this time, Cleo decides she wants to go. She doesn't want to just sit back and watch. Alex tells her she can't because of her paralysis, but she's determined to go anyway. Against Alex's wishes, she wheels over to the magic screen and touches something. She disappears into a mythical world, but her wheel chair stays behind. Alex is very worried, until Cleo finds out she is no longer paralyzed. She ends up in a world where 2 tribes are fighting to death, but she has the ability to stop the war. Alex tells her to come back, but she decides she has to help them first. Little did she know that helping would mean her death. She stopped the war by marrying the son of the opponents chief. She didn't know crossing the lake to go to the other side meant death. Did she die? If you haven't seen this episode, you will have to wait to see if she is in the next one.

Still trying to find their missing father, this time their quest brings Alex back to Ancient Greece where he becomes Orpheus. After his wife is bitten by a snake, Alex must go down into Hades to rescue her.

Their latest clue leads Alex and Cleo to Japan this time - right into the myth of Minokichi and the snow demon. While Alex is busy with an ice vampire and matters of the heart, Cleo learns more about her father's disappearance. She goes to her father's friend for advice on what exactly the Gorgos Stone is, and why she and Alex can't find any reference to Gorgos is any book.
