The Librarian: Quest for the Spear (2004)

Academically brilliant, socially awkward New york intellectual Flynn Carsen successfully postulates for a post as librarian. Only once accepted, he learns it's not really about managing books but mainly hunting relics. His first mission, in three parts, is for a magical Biblical spear, the key to unlimited destructive energy, which is broken into three parts, hidden in different countries, from Amazonia to Shangri La. He finds himself teamed up against a sinister, bloodthirsty serpent brotherhood with a martial arts specialist who failed to protect his predecessor Edward Wilde, or actually worse.
