Mitchell was an agent of Interpol in Paris, working at odds with bounty hunter, Reagan Cole, in pursuit of the international criminal, Jack Kendal. He attempted to head Cole off several times, threatening her with both the possibility of an arrest warrant, and or an airline ticket out of the country. He and Cole finally joined forces, however, and tracked their target to an anti-terrorism conference, discovering the bomb he had set in order to assassinate the presiding panel.
