Back from the 300-Meter Tower

The heroine is a wealthy heiress who hides her true identity and marries the wrong man. Five years later, her husband and best friend drug her and imprison her on top of an abandoned 300-meter TV tower. After waking up, she fights desperately to survive, breaking chains, climbing iron ladders, and even eating birds until she finally makes it back to the ground. Her father receives her distress video and launches an all-out search. But her husband and best friend arrive first to silence her. Just as danger closes in, her father arrives with his men and rescues her in time.
