The add is made in a similar manner of the previous SwiftVet add, with Kerry in the background making his Senate speach where he accused Vets of "ravaging Vietnam like Ghengis Khan" with snippits of former POW's one after the other in the forground saying that because of Kerry they were tortured by the Commies because of what Kerry did.
It ends with a POW saying that "Kerry betrayed us then, how can we trust that he wont betray us now" (or something like that)
