While driving through town, he catches a glimpse of a man in who looks exactly like his late friend Mac MacReynolds. Higgins, Rick and T.C. are concerned about the effect of Dianes suicide on Magnum, but Thomas is adamant that he isnt going around the bend and intends to prove to his friends and to himself that hes not going insane. But if Mac is dead, just who did Magnum see?
