A Marine patrol stops at Firebase Gloria at the start of the Tet Offensive during the Vietnam war. With the firebase attacked, the patrol remains to help defend it.

After listening to a story about camping read by her mom, Tina wishes that she could go camping someday. After Tina falls asleep, she dreams about a camping trip with Barney and the rest of the Backyard Gang. Barney takes the gang through different fun experiences from pitching tents to having a snack. In the mist of things, a storm comes around and Tina gets lost in the woods. Thanks to Barney's advice earlier of "Stay where you are, hug a tree and blow your whistle," everyone finds Tina and they continue onto more campfire fun. They even explore a cave where a bear lives. Back at the campfire, songs are sung around it and everyone learns how to make S'mores. After the trip is over, Tina wakes up and realizes it was all just a dream - and a magical one at that.
