Kathleen soon learns that Johnny is hard to contain, and his wild ways ger her evicted... and accused of kidnapping! After Johnny straightens things out, he quickly sweeps Kathleen off her feet, flying them both out of Palm Beach for a stay at his Kerrigan City mansion. But when thing go wrong, Seton must intervene once again to save Kathleen. And this time, Seton must reveal the truth about himself.
