Dean Martin is just fun to watch, but this is not very good. A fun early sixties kitch.
Leonard Maltin/Plot synopsis:
Malden kidnaps A-M's father, threatens to melt Washington, D. C. with a ``helio beam''; only Matt Helm can save both. (What if he'd had to make a choice?) Second Helm caper--after THE SILENCERS--offers one funny jibe at Frank Sinatra, absolutely nothing else. Sequel: THE AMBUSHERS.
