*P3W-924 is home to Ma'chello, an eccentric old man, and his unique inventions. One invention is a body-swapping device that is activated on an unsuspecting Daniel. Daniel finds himself in the body of a dying old man while Ma'chello, in Daniel's body, experiences Earth for the first time. O'Neill and Teal'c also fall victim to the device as their bodies are switched. When Ma'chello is finally returned to the SGC, he shows no remorse and insists the device is irreversible. Sg-1 must convince him to cooperatein an elaborate reversal, even though his own fragile body won't survive. *Source: Back of card
