A romance in which a seventh floor apartment represents heaven for a couple seeking to escap from time and the outside world.

Chico, a Paris sewer worker, desiring to be elevated to the position of street cleaner, burns prayer candles in the hope that God will give him another chance; he becomes embittered when his prayer for a blonde wife evokes no response. He rescues Diane, who has been victimized by her unscrupulous sister, Nana; and when denounced, Diane is saved from the police by Chico's claim that she is his wife. Their love is finally realized just as war breaks out, but their marriage is interrupted by the call to arms. Diane braves the war as a munitions worker and following the Armistice receives word that Chico is dead. He returns, however, though blinded, to restore the girl's faith and love.
