For centuries, the disappearance of 117 colonists from Roanoke Island has been this country's oldest mystery. Now, stonework experts Jim and Bill Vieira will use cutting-edge technology to take a deeper look at a mysterious inscription, which could finally lead to the truth about the lost colony.

Stonework experts Jim and Bill Vieira continue their hunt for the Lost Colony of Roanoke by analyzing the inscription on the mysterious Dare Stone against the 400-year-old historical record. By lining up passages on the stone with clues left behind by Captain John Smith of Jamestown, the Vieiras set out on a search for evidence that could reveal the location of the Lost Colony, and change American history.

In 1587, over 100 settlers landed in the New World to establish England's first permanent colony. Three years later, they had vanished... Josh Bernstein is on the trail of America's oldest missing-persons case. He flies high above Roanoke Island in a powered para-glider; climbs and cores a cypress tree to study the climate conditions the settlers faced; participates in an American-Indian powwow; and learns to cook as the local 16th-century natives once did. Finally, Josh travels back to England to trace the roots of a family that could be descendants of the Roanoke colony. Using DNA science, he makes a groundbreaking discovery--and, amazingly, it suggests that one of the 1587 lost colonists may have survived.

The notorious Tom Horn, hanged for a murder of a 14-year-old boy in 1903, is a pivotal figure in the taming of the Old West. A cowboy-turned-range-detective for big ranchers, he built a fearsome reputation as a professional hit man. Was he a cold-hearted assassin or a framed innocent man?

He was the Old West's most infamous desperado, yet we actually know little about his short life--and more important--his death. Now, New Mexico has reopened the investigation into Billy the Kid's crimes and mysterious death in 1881. Did Sheriff Pat Garrett kill him or fake the death and allow his friend to escape? We talk to those involved in the investigation, including Governor Bill Richardson, Pulitzer Prize-winning novelist N. Scott Momady, and historian Robert M. Utley to unravel the mystery.
