A woman from Tennessee goes missing while hiking the Appalachian Trail, which tests the wardens' search-and-rescue skills on land and from the air for more than a week.

In the Season 3 premiere, the wardens search under the ice of a frozen lake for the victims of a snowmobile accident; and the spring thaw comes with encounters with skunks and bears.

A Jet Ski hit-and-run accident sends the wardens on a search for a suspect with an arrest warrant; a man arrives in Maine after the Boston Marathon bombings in 2013 and leaves a suicide note.

A look at 24 hours of work by Maine wardens includes patrolling for smelt poachers at night; tagging bears with radio collars; and searching for a home invader with a K9 team.

A child on an ATV is trapped by a flash flood; and a teen flips his four-wheeler and must go to the hospital. Meanwhile, the wardens face their New Hampshire counterparts in an endurance competition; and two women who are wanted by the law are found during an investigation of suspicious activity.
