Suzy Martin is an American model , flavour of the month, big contract secured by her agent/ advertising man/ boyfriend Greg Miles. Suzy waiting in her apartment for Greg receives a phone call from a heavy breather, nothing is said, just the sound of breathing.

Next evening Terry Cleeves her ex turns up with an Italian called Bruno Varella, they are let in by the janitor as Suzy is out and Terry is an old friend.

Suzy and Greg arrive and Terry explains that he's here because Bruno wanted to meet her.
There is real tension in the air because Suzy is now working for Greg's ad agency rather than Terry's and he's been eased out of her private life too.
After everyone leaves Suzy on her own receives another phone call from the heavy breather, this time the caller speaks, saying, " Suzy....Suzy...I want you."
She is naturally disturbed by this.
Meanwhile outside in the street Greg leaving Suzy's flat is attacked by Terry and beaten to the ground.
Suzy calls the police and Constables Henry Venner and Dicky Lovell arrive at her flat. They give her the usual advice and she promises to contact them if he calls again.
They leave and then Suzy hears someone in her kitchen , entering through the door leading to the fire escape stairs on the side of the building. It's Greg, bruised and bloodied. Suzy administers first aid and suggests he calls the police, but Greg declines, he's a married man and doesn't want it known he's been here.

Back at his flat Terry comes clean and admits to Bruno Varella that he attacked Greg , jealousy got the better of him.
Bruno seeing blood on Terry's hands says he guessed that's what happened and advices him to give Suzy up, reminding him of the English expression of girls being called birds, well Suzy has flown his nest.
