I highly recommend this video. This is a must-see video and it should be shown in all youth groups.
The DVD describes itself as follows:
See what happens when eight ordinary teens set out on a mission to meet the underground church in Vietnam. Travel with The Voice of the Martyrs and a group of American and Australian teenagers as they journey through cities and jungles in order to witness the everyday life of the Vietnamese underground church.
These teens come from the nominal, lukewarm Christian churches so common in America, Europe, and Australia, but by the end of their journey (which includes smuggling Bibles) you see their lives transformed by the realization of what it truly means to be a Christian when your life and liberty are at stake.
The two hour DVD is broken into four half hour episodes and will keep the attention of even its younger viewers.
*** Update ***
The Voice of the Martyrs has made this video available again. You can order it here.
