This book contains a series of measures that will prepare you for disaster scenarios, teach you how to survive in any environment, and help you defend yourself and your loved ones in times of crisis.

The author, a retired member of the elite SEAL team of the US Navy, has relied on the training, missions, and protocols of special forces to create the skills in this book. Many skills are inspired by situations we read about in recent newspaper headlines. This manual aims to help you deal with a range of dangerous situations, from a wild boar attack and being stranded at sea, to deciding whether to try to escape, hide, or attack a terrorist.

The hundred survival skills, which are based on low or "non-existent" technology tools (because the last thing you need when facing immediate danger is finding and activating high-tech devices) include:
- Searching the house for potential intruders
- Starting a fire with the help of a mobile phone
- Handling objects that have penetrated the body
- Surviving a snowstorm or tsunami
- Fortifying doors that open outwards
- Finding food in the desert
- Defending a ship against pirates
