MacGyver's best friend falls to her death while mountain-climbing with him. MacGyver has no time to mourn when Murdoc shows up looking for revenge.
While scaling the cliff face known as "The Widowmaker," Mac loses his best friend. Before he can properly grieve, he is forced to run from an old enemy who is now hunting him down. With the help of a colleague, Mac finds his way back to the Widowmaker and fighting for his life on the same ledge that took his best friend.—clbw
