In this crime story, surprisingly, neither the all-powerful criminals nor the spies or saboteurs are pursued, as was once common. The plot is almost mundane: someone unwittingly siphoned off alcohol from a tanker, unaware that it was deadly methyl alcohol, intended for industrial use. Finding out where the poison has been transported and which people it endangers requires painstaking work.
