What sort of fatal shooting leaves no bullet hole or gunpowder mark, and makes no blasting sound? That's the question faced by a college football hero in this tale of murder and conspiracy set on a New England campus. As a group of people gathered in a mansion on the school's grounds start getting murdered by a hooded killer, the gridiron giant tries to find and stop the madman. Charles Starrett, Marion Shilling, Robert Warwick star. Standard; Soundtrack: English.
