Lost City Raiders (2008)

In the dystopian world of 2048, our planet is in the throes of a global warming catastrophe, as the relentless rise of sea levels submerge city after city. Amidst this chaotic new world order, John Kubiak, a seasoned salvage expert, and his adopted sons, the daring Jack and the sagacious Thomas, scour the sunken ruins for lost treasures, their survival hinging on what the drowned world yields. However, their lives take a dramatic turn when they're entrusted with a clandestine mission by the New Vatican's enigmatic Cardinal Battaglia. Their task - to retrieve the legendary scepter of Sobek, an ancient relic believed to possess the power to control the sea levels. As they navigate through submerged labyrinths, this mission becomes more than just a treasure hunt; it is a race against time and a ruthless adversary. Their competitor is the nefarious real estate tycoon, Nicholas Filiminov, who, armed with ulterior motives, is hell-bent on claiming the relic for himself. Adding a layer of complexity to the high-stakes quest is the involvement of Giovanna Becker, Jack's ex-lover. Filiminov, exploiting her expertise in geological sea control, has manipulated her into joining his side, promising to fund her research. As the Kubiaks delve deeper into their perilous endeavor, they face not only the mystery of the ancient scepter but also the turmoil of betrayal, their mission becoming a test of their endurance, loyalty, and the will to protect humanity from a watery oblivion.
