Our main character is Nate Drake (Tom Holland) - from the "Uncharted" video game series. He and his older brother were orphaned, and thieves even in their youth. But his brother runs away after a botched robbery when Nate was ten, leaving a long shadow over the rest of our protagonist's life. Now in his mid-twenties, Nate is approached by Sully (Mark Wahlberg) who's interested in recovering the same treasure that Nate and his brother dreamed of retrieving. After some disagreements, they set out together to pursue the treasure. They cross paths with multiple other treasure hunters, all of them even less trustworthy than Sully.
The double-crosses and misplaced trust are never-ending. The defiance of physics is ... well, awful, although not quite as bad as I expected. The movie tries hard to be the next Indiana Jones, but instead falls short of Benjamin Franklin Gates (and if you don't recognize the reference, that's kind of the point).
