Synopsis by Hans J. Wollstein
In chapter six of S.O.S. Coast Guard, the Adamic's boilers explode but Terry (Ralph Byrd) manages to get out of the room in time to rescue the trapped crew. One of Boroff's lackeys, Black (Robert Walker), is found wounded and is about to be questioned when silenced forever by Thorg (Richard Alexander). But before he expires, Black manages to whisper the words "pier" and "port." Guessing that Boroff (Bela Lugosi) has changed his modus operandi, Terry hastens to the small town of Pierport, where cases of light bulbs are about to be shipped out by rail. One of the bulbs breaks, however, and is revealed to contain Boroff's devastating disintegration gas. Attempting to disperse the vapors, Terry positions himself directly below a water tower that threatens to topple.
