Murderers' Row

On a quest for world domination, Julian Wall (Karl Malden) and his evil cohorts in the Brotherhood of International Government and Order kidnap Dr. Solaris (Richard Eastham). Solaris invented a heliobeam, a weapon capable of cataclysmic destruction. It's up to secret agent Matt Helm (Dean Martin) to rescue Solaris before he is brainwashed into using the heliobeam. Helm poses as a gangster, seducing Solaris' daughter, Suzie (Ann-Margret), along the way.
