The Price Mark(1917)

Broke and stranded in the Big City, Paula Lee (Dorothy Dalton) willingly becomes the mistress of "love 'em and leave 'em" playboy Fielding Powell (William Conklin). In spite of himself, Powell falls in love with Paula, and just before leaving on a business trip, he promises to marry her upon his return. In the meantime, however, Paula falls in love with dedicated charity doctor D. Melfi (Thurston Hall).
