Faithless is a much better than average variation of the depression-era standard plot of "real men don't sponge off of rich wife."
Socialite Carol Morgan and Bill Wade are deeply in love, but Carol also loves her money and lifestyle and is confident that she will always have them. They part ways and the Great Depression finally wipes out Carol's fortune. What follows is Carol's increasing desperation to live, redeem herself and eventual re-establishment of a relationship with Bill. The path has many struggles.
