Disgraced
archaeologist Luke Purdue steals a painting from criminals in
Thailand and foils the mysterious Esme and her henchmen, who attempt to seize the painting themselves. In
London, Luke surprises his sister Charlotte, a museum curator who is divorcing her unfaithful husband Harold. Stealing another painting from the museum, Luke baits Charlotte into fleeing with him and his partners Murphy and Deb, revealing that he has continued their late father's legacy of treasure-hunting. Questioned by
Interpol Inspector Jamal Abbas, Charlotte is fired and confronts Luke at his hideout, where she is introduced to Owen Carver, a wealthy
corporate raider with terminal cancer who is financing Luke and his team's search for the fabled
Fountain of Youth. Owen entices Charlotte to join the team with the promise of giving her a powerful lawyer to gain custody of her son. Their father's notes reveal that a
secret society known as the "Protectors of the Path" has concealed the Fountain for centuries, but a faction who disagreed with the Path's mission hid clues in six historic paintings Luke has stolen, including
Rembrandt's
Head of Christ from the museum. Charlotte admits that the
Head of Christ is a duplicate, and reluctantly joins her brother's quest. The real painting was lost in the sinking of the
Lusitania, and the team raises the first-class section of the ship to the surface. Recovering the painting from
Alfred Gwynne Vanderbilt's safe, Luke and Charlotte are held at gunpoint by Esme and her fellow Protectors, but escape the sinking wreckage with the painting. The team returns to London and the paintings' clues point them to the
Wicked Bible, but their hideout is raided by Abbas before they are all ambushed by the Thai gangsters. Provoking a shootout, Luke escapes with his team. Harold accepts a job overseas, leading Charlotte to bring their son Thomas with the team to
Vienna. Examining the Wicked Bible at the
Austrian National Library, Luke is again ambushed by Esme, who warns that the Fountain hides a terrible power he does not understand. He and his team steal the Bible, but Charlotte refuses to further endanger her son and storms off. Thomas convinces her to return, having deduced that the code hidden in the Bible is musical notes, which the team identify as an ancient song honoring the
Seven Wonders and realize the Fountain is located in a newly discovered secret passage beneath the
Great Pyramid of Giza thanks to
muography. Esme meets with the Elder of the Protectors of the Path, who reminds her that she must do whatever is necessary to keep the Fountain from being unearthed, for humanity's own protection. In
Cairo, Carver secures the pyramid with his heavily armed mercenaries, forcing Luke, Charlotte, and Thomas to unlock the secret passage. Abbas arrives with a convoy of Interpol agents, only to be outgunned by the mercenaries, and Deb is wounded as she and Murphy try to intervene. Esme and her fellow Protectors overpower Carver's men, and she and Abbas join forces, pursuing the others into the passage. In the depths of the pyramid, Luke and the others discover the Fountain. Charlotte realizes Carver is not sick and simply wants to hoard the Fountain's power for himself, but Carver shoots Luke in the arm, demanding he drink from the Fountain to test its effects. A drop of Luke's blood causes the mystical waters to tempt him with a vision of eternal life, at the cost of Charlotte and Thomas' own lives, and he realizes the curse of the Fountain: whatever energy he is granted will be transferred from those he loves most. Luke refuses to drink, and his wounds are instantly healed. Abbas and Esme reach the chamber just as Carver drinks the water but, as he cares only about himself, he is drained of his own life force. Esme uses a key from the Elder to seal the chamber, trapping the rapidly aging Carver inside as the others escape. Charlotte convinces Abbas to blame Carver for their crimes, and Esme kisses Luke, warning that their paths will cross again if he continues to search for forbidden treasures. Luke reunites with his team, and Charlotte and Thomas suggest their next adventure. ==Cast==
