As the music video shoot is underway, the lead singer of SM6, James, finds a strange-looking parchment paper in a hidden compartment of the tall ship. While everyone is busy rehearsing, James curiously reads the words on the map, and a sudden gust of wind spills his drink on the paper. The liquid activates the incantation, and the skies turn dark as a swirling vortex appears out of nowhere. The ship is dragged into the swirling waterspout and vanishes.
When SM6 regains consciousness, they find themselves in a vastly different world. Instead of the modern skyline and cityscape that surrounded them earlier, they now see only the vast ocean and a pirate ship in the distance. As they approach the strange vessel, they realize that they have been transported back in time to the 17th century.
The pirates on the other ship, led by the ruthless Blackbeard, immediately board the SM6 vessel and take the band as prisoners. However, SM6 realizes that the treasure map they have is of utmost importance to Blackbeard, who is convinced that it leads to the greatest loot in the region. James reveals that the incantation on the map was responsible for their time travel, and Blackbeard demands that they take him to the location.
Fighting their way through dangerous waters filled with perilous sea creatures, the group finally reaches their destination, an uncharted island. Here, they encounter the infamous Kraken, a gigantic sea monster that challenges the crew to a perilous battle. Despite their fear, the band members stay focused and manage to defeat the Kraken.
On the island, SM6 discovers an ally in Anne Bonny, a fierce female pirate who joins forces with them. Together, they navigate through traps, treacherous terrain, and nearly-impossible obstacles to uncover the treasure. However, their success comes at a high cost when Blackbeard betrays them and leaves the band on the island, unable to return home.
As they grapple with the sudden realization of their predicament, the band members must use their wit, courage, and newfound skills to survive in the treacherous waters filled with cutthroats and traitors. The journey brings them closer together, and they finally realize that the map was never about the treasure but about the adventure itself. As they rebuild their ship and plan their escape, they carry with them the memories of a lifetime, the bonds of friendship, and the spirit of adventure that will stay with them forever.
