Montana Jones, an adventurous anthropomorphized big cat, navigates the 1930s Boston coast alongside his cautious cousin, Professor Alfred Jones, pursuing a shared mission to recover and protect endangered historical treasures for public preservation. Their expeditions rely on Montana’s earnings from his aunt Agatha’s restaurant, which fund repairs for his temperamental Supermarine GS waterplane, Ketty—a vital yet unreliable vessel central to their global quests.

Bold and thrill-seeking, Montana charges headlong into perilous unknowns, counterbalancing Alfred’s methodical academic approach. Their efforts pit them against Lord Zero, an eccentric rival art collector determined to seize artifacts for personal gain, driving Montana’s resolve to outmaneuver exploitation through daring escapades.

Joining their ventures is Melissa Thorn, a multilingual reporter and diplomat’s daughter, whose ties to Alfred’s mentor, Professor Gerrit, surface through cryptic clues relayed via gramophone records. While Montana’s camaraderie with Melissa occasionally flickers with unspoken affection, their focus remains fixed on unraveling mysteries.

Between expeditions, Montana’s coastal home doubles as a strategic hub, where resourcefulness offsets Ketty’s mechanical woes and tight budgets. His tenacity in overcoming these hurdles underscores a broader crusade: safeguarding cultural heritage against those who would profit from its loss, cementing his legacy as both a maverick and a guardian of history.
