What is the main conflict in The Frogs, and Other Plays. Translated with an Introd. by David Barrett by Aristophanes?

In the play, The Wasps, one of the main themes is centered around the debate regarding the inversion of slaves and masters. Philocleon believes that he is the master of the demagogues as a juryman, but his son shows him that he is, indeed, really a slave. Furthermore, it is the son, who should show deference to his father and the other elder wasps, who convinces them to give up their ways and ultimately is able to make his father conform to his will. Eventually going so far as to lead his father to do the one thing he has never done, in this case, cast a not guilty verdict and acquit a defendant.
