Though "blessed" with a complex title, which translates as Marriage with Limited Liability, this German comedy was adapted from the more simply titled stage play Causa Kaiser. Composer Georg Kaiser is unable to secure a divorce from his wife, so he "lives in sin" with his singer-sweetheart Causa. The girl's wealthy uncle dies, leaving her millions -- provided she is married to Georg Kaiser. Hoping to take advantage of a legal loophole, Georg seeks out another man named George Kaiser, intending to marry him off to Causa so that she can collect her legacy. Georg Kaiser # 2 is a middle-aged naif who can't understand why his new bride is so cold to him. When he finds out he's been duped by Kaiser #1, Kaiser #2 finds solace in the arms of another woman closer to his own age, which somehow leads to a happy ending for all concerned.
