Riddick attempts to rebuild his homeworld. But Vaako is proving a greater adversary than Riddick expected. He needs the help of a princess if he expects to ever live free.

A broken digivice traps a young boy named Andrew Roth in the Digital World and binds him to a less than enthused Renamon. As they look for a way to return the boy home, the two discover his appearance may not be the accident it first seemed; and that they alone stand against a dark force that has already gathered its army.
