On a train from Constantinople to Paris
in 1914, Mary (an Alsatian girl with a theatrical troupe), two
American youths (Bill and Al), a German, a Frenchman, a Russian, and
a minister become involved in an argument over Christianity; the
discussion is abruptly terminated by a collision. All find
shelter in a nearby inn where a fight ensues. Hilda, the
innkeeper, contrives the escape of Travis, Mary, and Al as a cavalry
troop arrives with the news that war has been declared.
In Paris, Travis and Mary fall in love,
and soon Al enlists, as does Travis. Meanwhile, Mary becomes a
canteen dancer searching for Travis. When Mary repulses a
Russian's advances, he causes her to be incriminated as a German
spy; but on the day set for her execution, Travis recognizes her at
the last minute.
Comparison is made at this point between
the World War situation and the Biblical account of the Flood.
At the Festival of Jaghut, the revelries are to climax with a human
sacrifice, while Noah and his small following reside in primitive
simplicity on the outskirts of the city. A group of carousing
soldiers see Miriam, betrothed of Japheth, the youngest of Noah's
three sons, and carry her away for the King. The King is
struck by her beauty, and he orders that she be prepared for the
sacrifice.
Meanwhile, Noah receives a message from
God directing him to build and provision the Ark. Noah
interrupts the festival, warning of the consequences. As the
high priest prepares to kill Miriam, a bolt of lightning strikes him
and a second bolt topples the idol. As water floods the
temple, Japheth's sight is miraculously restored and he rescues
Miriam. Borne on the waters, they reach the Ark and are
received by Noah.
Reverting to the modern story, Red Cross
workers are busy administering to the war injured when a messenger
arrives, bringing news of the Armistice. Mary and Travis,
though tattered and dirty, join in the celebration of a new era of
peace.
