The Adventurous Sex (1925)

"She's "Smart Baggage!" With 'Broadcasting Eyes' and as full of Syncopation as a Saxophone."

A young man spends so much time at work on his airplane that he neglects his girl. She goes out on her own to live the high life, but her reputation is soiled by an adventurer. The young woman resolves to kill herself, and throws herself into the water rushing towards Niagara Falls, but is saved at the last minute by her former sweetheart.
