Was ist Liebe?.

Doris embodies innocence and kindness, sacrificing herself for everyone. Day and night, she cares for their seriously ill mother, while her older sister Carmen prefers to go her own way. After their mother's death, Carmen takes her to the vaudeville theater, where she becomes a star but remains unaware of the dangers this world holds. For a small fee, her sister sells her to Fredy, who eventually abandons her while she is pregnant out of wedlock. Carmen Cartellieri and Doris Kay portray this contrasting pair of sisters. Innocence and selflessness clash with amorality and egoism: the decline of morals and its consequences are vividly depicted. (Filmarchiv Austria)
