After aliens fail to effectively manage their time-space communications devices and botch an attempt to contact rocket scientist Dr. Russell Marvin and his charming wife Carol, they start to destroy Earth targets, suck the knowledge out of military brains, and issue ultimatums. Fortunately, Dr. Marvin and his fellow scientists have a few tricks of their own.
