The episode begins with Anais and Jamie in the principal's office, the former wondering why would they be there. Principal Brown angrily tells them that there was a computer virus in the library (in an odd way that Jamie does not understand, which Anais has to correct), and if neither of them confesses which had done it, they would be expelled.
After they exit the principal's office, Anais suggests that they should work together to find the culprit, and possibly make a friendship along the way, greatly exaggerating the statement. Anais notices Jamie has left and is relieved she did.
In the library, Anais tries to clarify that Jamie did not do it by asking her to check her mailbox. Strangely, Jamie walks out of the library, goes home to check her actual mailbox, and comes back to school. Anais comes to a conclusion that Jamie did not do it, since she too, could not understand tech talk. Jamie clarifies that Anais would not have done it, since she is incapable of doing anything bad. Anais tries to prove her wrong, but messes up all the remarks.
In the computer area, Anais tells Jamie to look at the desktop, which has all the "sick" computers. Jamie again misunderstands and looks at the actual desktop, which Anais points out. This angers Jamie, and she prepares to punch Anais, but stops when she notices a security camera.
In Principal Brown's office, Anais and Jamie look at the security tape, but it is all fuzzed up. Jamie threatens the monitor, and it comes back on, revealing Bobert in the area. They go out to the playground to confront him. Bobert starts telling them that he did not do it and who did, but someone throws a dictionary on him from above. They try to find out who did it, but see that inside the dictionary, someone has written "Give up... or else."
Anais and Jamie return to the library and ask the Librarian who the last person was to check out the dictionary. The Librarian tells them it was Gumball and Darwin. Although, while the Librarian is telling them about what happened (through notes), Jamie realizes it was the same writing in the dictionary, and throws the dictionary at her. Jamie shows Anais, but the Librarian gets up and starts trying to attack Anais and Jamie. Jamie starts throwing books, but they are short and light. Anais runs over to the classics, and uses a story to conjure up weaponry. Soon Anais and Jamie are in a classics feud with the Librarian, and get cornered. The Librarian tells them the books were not being checked out, and so she tried to strike the computers down. Anais throws a large study guide at the Librarian, knocking her out.
Anais and Jamie get out of the principal's office, triumphant that they cracked the case, and start making jokes. Anais thinks this makes them buddies, but Jamie says no, and that it only makes them friends. Anais is overjoyed, but does not know what friends do, ending the episode.
