Pete Wilder just saved Richie from an attack by some guys wearing Watcher tattoos. Or did he? Nothing is what it seems, and MacLeod becomes increasingly wary of Pete, despite Richie's protests that the guy is his friend. When MacLeod's mistrust gets the possibly innocent Pete killed, Mac becomes increasingly unsure of himself. Unknown to MacLeod, his old enemy Horton is pulling all the strings. Horton is secretly training escaped killer Lisa Halle to go after MacLeod while he's troubled and vulnerable.
