Hosts Jason Chambers and Bill Duff travel to Israel to study one of the deadliest and most effective Martial Arts in the world, Krav Maga. Krav Maga was designed in the 1940s by Imi Lichtenfeld specifically for combat situations and self-defense. Krav Maga was created on the basis of "no quarters", which means that during war no one will be taken prisoner and that all enemies must be killed. Krav Maga was later modified for the Israeli Defense Forces as well as ordinary civilians which resulted in the creation of the Israeli Krav Maga Association in 1978 and became the form of Krav Maga that is now taught all around the world. Traveling through the most sacred religious areas in the world, Jason and Bill learn techniques to escape deadly chokes, deflect weapons and to perfect the vicious counterattacks this brutual Martial Art is known for. To end their journey, Jason and/or Bill will fight against a full unit of high level ranked Krav Maga professionals.
