Long before he became the professor of later Robert Langdon stories, this series imagines his first brush with a conspiracy that reaches into the heart of Washington.
What is Dan Brown's The Lost Symbol about?
Adapted from Dan Brown's novel, the show follows a young Harvard symbologist thrown into a race against time after his mentor is kidnapped. Ashley Zukerman plays the lead, working through a chain of hidden codes and historical puzzles scattered across Washington landmarks. Valorie Curry, Sumalee Montano, Rick Gonzalez, Eddie Izzard, and Beau Knapp round out a cast caught between government secrecy and a shadowy plot with roots stretching back centuries. Produced in Canada, the series runs as an hour-long drama blending mystery, action, and adventure across its season.
About the cast
Ashley Zukerman carries the central role as the puzzle-solving Langdon, while Eddie Izzard brings a very different register to the ensemble as a figure entangled in the wider conspiracy. Valorie Curry, Sumalee Montano, Rick Gonzalez, and Beau Knapp fill out the supporting roles that keep the investigation moving between government offices, museums, and hidden chambers.
Context & significance
The series sits within the extended world Dan Brown built around symbology and code-breaking thrillers, though it tells an earlier chapter than the feature films that introduced Langdon to wide audiences. Setting the story in his student years lets the writers build a fresh mystery rather than retread the novels already adapted for the screen, while keeping the same taste for puzzles hidden in plain historical sight. That structural choice also gives the ensemble more room to breathe than a two-hour film would, spreading the investigation across a full season instead of compressing it into a single sitting.
