Engrossed in the perfection of a new high power explosive, the husband seems to neglect his wife. She is further piqued by the introduction into their home of a man whose presence is unexplained, but who is really a Secret Service operative guarding the invention. The Government has asked that the wife be kept in ignorance. In this frame of mind the wife lends a ready ear to Aachen, who suggests that the husband be taught a lesson by the abstraction of this all-absorbing formula. Through this means he gets the formula, but in the end the Government gathers him in, and the only permanent result is a needed lesson to the innocent little traitor.
