Take Back the Night

When Immortal Ceirdwyn and her mortal husband are gunned down by a street gang, she calls upon her skills as an ancient Celtic warrior to exact her revenge on the members of the gang, one by one. At the racetrack watching Richie's success at racing, MacLeod befriends a young pickpocket, the brother of one of the gang members, and learns of the killings. MacLeod, who has known Ceirdwyn since before they helped smuggle Bonnie Prince Charlie out of Scotland in 1746, feels he must stop Ceirdwyn and make her see that revenge is not the answer — a lesson she helped MacLeod learn in the bloody aftermath of Culloden. In return, Ceirdwyn helps MacLeod see that, although loving a mortal can be dangerous for the mortal, it is the mortal who must choose whether to take the risk. MacLeod calls Anne. Meanwhile, Richie ""dies"" in a firey crash during a race, a crash that also takes the life of the champion, Basil.
