The Sweetest Sting - S2.E11

A demented bee keeper, McCabe, uses a cursed antique beehive in a complicated scheme. First he turns loose the bees in the beehive, which kill someone and make a blood-honey. Then McCabe sells the honey to dying businessmen in return for lots of money. The businessmen must then kill their ""replacement"", and they take over their victims' bodies, abandoning their old lives. However, they have to keep eating the blood-honey (and paying McCabe more money) to maintain the bodies' health, or they revert back to their original dying infirmity. The trio get wind of the scheme, and kill McCabe with the help of one of the businessmen who finds that his new life isn't worth the loss of his loving, abandoned wife.
