This is a summary of the video:
The video talks about six cases of people who sent hidden messages to ask for help or communicate information when they were in danger or captivity. The cases are:
- Jeremy Denton, a US pilot who was captured by the Vietnamese and blinked "torture" in Morse code during a propaganda interview.
- A woman who ordered a pizza online and wrote "please help, call 911" in the comment section to escape from her abusive boyfriend.
- John Prior, a British soldier who was imprisoned by the Germans and wrote secret messages in his letters using a complex code that he later forgot.
- Alexis Casdagli, another British soldier who was captured by the Germans and embroidered a tapestry with Morse code saying "God save the king" and "F*** Hitler".
- A 911 operator who received a call from a woman pretending to order a pizza but actually asking for help because her husband had locked her in and threatened her with a knife.
- A note written in Chinese found inside a Walmart bag by a customer, claiming to be from an inmate of a prison camp who worked under harsh conditions and asked for help.
