Most people think of Lake Clark as an exclusive slice of remote Alaska, but a trip to Port Alsworth can cost you thousands of dollars in travel and lodging, flying in from Anchorage.

But for 16 weeks every summer, groups of wounded veterans and their spouses arrive, 10 couples at a time, for an all-expense paid trip to heal from the trauma of war.

In this week’s Frontiers episode, “Hope for Veterans: A Healing Journey,” we bring you an in-depth look at “Operation Heal Our Patriots,” a program run by the evangelical Christian group, Samaritan’s Purse.

Here’s a preview of this week’s Frontiers tribute to Veterans, which airs on Sunday, November 12 at 4:30 and 10:30 p.m. You can also watch Frontiers on Sunday at 8:30 a.m. on GCI Cable 907. This week’s Frontiers also features an interview with Franklin Graham, the president and founder of Samaritan’s Purse.
