During the American Civil War, the railroad was becoming more and more of a necessity. The railroad allowed quick transportation of troops and supplies to backup attacked areas. To stop this, the Union and the Confederates tried to gauge when an enemy train was coming and destroy it. The Union could do it better though. They created a simple but effective device, called the Pin Pointer, by using a series of mirrors scattered across the country that could carry the reflected images all the way back to the Pin Pointer. The Pin Pointer could accurately spot anything within 1000 miles.
The Pin Pointer had been hidden for a long time until 1914. A German spy ring named "Sky Watchers" recently discovered the Pin Pointer. They found they could see US military activity. But they weren't the only ones who discovered the Pin Pointer. Young adventurer Tommy Skills found out about it too. To save the US from their secrets leaking out, Skills must destroy the Pin Pointer and destroy the Sky Watchers.

Nice use of the Minifigure Series stands at the top, I love the shotgun blast effect and the cactus as well. A may have to swipe that cactus technique sometime, if that's fine with you. ~Ryan
