An American singing star in London tries to reclaim the son she gave up for adoption.

While in London for an appearance at the Palladium, celebrated singing star Jenny Bowman visits British surgeon David Donne in an attempt to renew their former relationship. Years before, they had met in New York and fallen in love, but Jenny had chosen a career over marriage to David. When a son, Matt, was born, she agreed to let David take him back to England to be raised as his adopted child. Jenny begs David, now a widower, to let her see their son, and he reluctantly agrees to a single meeting. Excited by the presence of a great star and captivated by her charm, Matt defies his father's orders and allows Jenny to spend all her time with him. The boy's disobedience precipitates a bitter quarrel between David and Jenny, and Matt learns that Jenny is his mother when he overhears them arguing. Matt is then told he must choose between his parents, and when he rejects Jenny, she goes on a spree and ends up in a London hospital. David visits her and promises to take her to the only place she can find happiness; he drives her to the Palladium, and as she is swamped by admirers, Jenny admits David is right.
