Azure Express was based on Budapest-Wein. Hungarian film favorites Antal Pager and Klari Tomay star respectively as a schoolmaster named Thomas and a forlorn waif named Tery. On the eve of his weding, Thomas saves the suicidal Tery from a watery grave. He gives her shelter for the night (carefully observing the proprieties, of course), and nearly misses his own wedding as a conseuqence. While on his honeymoon, Thomas meets the impoverished Tery again, and again takes pity on her, missing his train as a result. One thing leads to another until Tery persuades Thomas to pose as her husband for the benefit of her snooty relatives. He is forced to maintain the deception right up to the honeymoon chamber, as the audience wonders if this mess will ever straighten itself out.
