Matchless takes you to the fascinating world of crime where money and power are more valuable than life. Power in this action packed movie is bequeathed to an American Journalist Perry Liston (Patrick O'Neal), who finds himself in possession of a ring that makes him invisible. This newly acquired asset sends him deep into the throes of a gang. He intends to find out the dark and dirty secrets of its criminal master-mind, Gregori Andreanu (Donald Pleasence). Gregory is an enigma to many, a terror to all, and a tough nut to crack. Success is slippery, but failure is not an option for the novel spy on whose hands rest the key to opening a Pandora's box. His pursuit is crowded with shadowy agents whose sole aim is to acquire the ring at all costs. This cat and mouse chase that ensue in the pursuit of the ring by the foreign agents, is exhilarating to watch.
