The famous actress Paula Corvey loves the young racer Werner Bruck. One day, Paula's 18-year old daughter returns unexpectedly to her mother. She was living with her father, Paula's ex-husband, but she's run off to Paula, because daddy wouldn't let her become a hot-to-trot actress like mama. Paula just doesn't know what to do. That she's the mother of a grown up girl is something she desperately wants to hide from Werner (no, honey, I swear: you don't look a day over 17 ... uh huh). So, to cover her little horny tracks, she tells Werner that Eva is her cousin. The plan backfires (ha ha!), when Werner falls for the "cousin". When Werner finally discovers the truth, a conflict develops (duhh!), which can only be solved by Paula finding a man her own age (thank you).
