Marshal Campbell, an 11 year old ranch hand, lives alone with his dad, Tex, in rural West Texas. He and his dog Boots, a furry red golden retriever mix, don't need any help finding trouble in the rugged and sandy landscape. The hot summer day begins like any other, as Marshal and Boots feed the guineas and head out across the pasture looking for adventure. What they don't know is that a rhumba of rattlesnakes awaits them, hissing and rattling like a Friday night drumroll. Their day-long adventure takes them into the next week, and the outcome is not guaranteed survival.
