While being pursued for a crime he did not commit, he is kidnapped by a group of criminals who suspect him of being involved with double Agents. Otley manages to escape, but cannot avoid getting into one nearly fatal crisis after another, as Police and foreign Agents chase after him. It is a wild week of misadventures which he will never forget.
