In a horror movie, it could be that the girl is a victim of a deranged killer.

It might be a horror - themed story. The girl is tied and gagged, perhaps by some deranged person. The treadmill could be part of a sadistic plan, like she is forced to be near it for some psychological torture. The story could then be about her struggle to escape this terrifying situation.
In a more action - adventure context, perhaps the girl is a spy who has been captured by the enemy. The tying and gagging on tiptoes is a form of torture or interrogation technique. But she is a strong - willed character, and she uses her wits and any available resources around her to outsmart her captors and escape.
One possible plot could be that the girl is a witness to a crime. The criminals tie and gag her in the changing room to stop her from reporting what she saw.

One possible plot could be a mystery thriller. The girl is tied and gagged during a webcam session, and it's part of a ransom situation where the kidnappers are using the webcam to send messages to her family for money. Another could be in a horror context, where she is a victim of a deranged person who likes to terrify his victims on webcam.

In a prank video for a school project, a girl agreed to be the subject. Her friends tied her up and gagged her gently. Immediately, she felt embarrassed as she knew she looked silly.

By the end of the filming, the embarrassment had turned into amusement and she was proud of being part of such a creative project.
Maybe she's a hostage in a robbery gone wrong, and the key is to the locked door where the robbers have stashed their loot. If she can free herself, she can alert the police.

One possible story could be in a mystery or thriller context. Maybe the girl is a witness to a crime and the criminals tie her up and sock - gag her to keep her from screaming or alerting the police. Then, a brave hero comes along to rescue her.
One possible plot could be that the girls are witnesses to a crime and the criminals tie and gag them to prevent them from talking or escaping until they can figure out what to do with them.
