LOGLINE:
When Shawn's adventurous and notoriously unreliable Uncle Jack comes to town claiming he has a map to ancient hidden Spanish treasure, Shawn, Gus and Henry find themselves in a life or death chase for treasure with a shady group of raiders who will stop at nothing to get to the prize first.

SYNOPSIS:
Shawn, Gus and Henry return from a night at the movies to find that Henry's younger brother Jack is back in town and has broken into the house.  Shawn finds him crouched by the coffee table in the living room.  The guys are elated to see him but Henry is less than thrilled.  Where they have always been enamored by Jack's wanderlust and fantastic stories of his worldwide adventures, Henry has always known his younger brother to be unreliable and irresponsible.  Jack always wants something, and when Henry questions his motives for being back, he confesses that he wants their help to find the French pirate Bouchard's hidden treasure.  Henry claims the legend of Bouchard's cache of stolen Spanish gold is just a story and the treasure doesn't exist.  But Jack proves him wrong as he pulls out an ancient treasure map he discovered while traveling in Argentina.  See, Bouchard, after a battle with the Spanish fleet and the Chumash Indians, made off with the gold then disappeared at sea, only to turn up in Argentina years later.  Now Jack, armed with a map and a psychic detective, is positive he can find the treasure, and offers Shawn and Gus a fifty-fifty split.  They jump on board.

The next morning, they meet Jack at a mission, where they impersonate professors and are able to gain access to the mission's private art collection.  According to Jack's research, an important clue is hidden there somewhere and it has to do with the number 152.  When Gus asks why they just don't use the map, Jack confesses that a part of it has been ripped away – the place that tells them where to start.  But he knows with Shawn's psychic ability and the clues hidden in the mission, they will be able to figure out where to go.  Shawn looks at the map and sees hidden in the words letters that spell out the French word for "painting."  They find a painting of Bouchard in the collection that, when lined up with the map, points to a lighthouse as their first clue – a lighthouse with the historical designation number 152.  But when they get to the lighthouse, they are immediately set upon by a group of armed men, who, it turns out, are Jack's original partners.
