The last time Richie Ryan saw Duncan MacLeod, MacLeod was about to take his head. He was stopped by Dawson's bullet, but Richie's world was shattered. Now Richie's back -- kicking butt and taking heads. One of those heads belonged to Carter Wellan, and now Wellan's good friend Haresh Clay is out to avange his comrade. MacLeod has his own long-time grudge against Clay, who humiliated and destroyed one of MacLeod's finest teachers. MacLeod must try to rebuild Richie's trust while they vie to be the one to face Clay in combat.

Of all the gin joints in all the towns in all the world, Dawson's high school sweetheart BETSY walks into his. Meanwhile, MacLeod's got his hands full with Johnny K, a teenaged mobster wannabe when MacLeod knew him during Phrohibition who's now a cold-blooded assassin. The only rules Johnny K knows are the rules of the street, and MacLeod's going to have to play by them if he wants to keep his head.

MacLeod knew him as Melvin Koren, a desperado who left a trail of death and fire across the Old West, but Cassandra remembers him as an evil far older. He is Kronos, leader of the Four Horsemen, mounted Bronze Age raiders who murdered, raped, and pillaged their way across two continents. Never was a band of Immortals more cruel or more feared. He destroyed Cassandra's people and she's been hunting him across the millenia. But Kronos has a different target now -- Methos.
