Dr. Lazarus.

Pilot episode of a never-produced horror short series: In 1870, a group of Argentine landowners founded the Logia del Eterno Retorno, sponsoring the research of Poison, a British veterinarian seeking immortality. However, a yellow fever epidemic interrupted his plans. Before dying, Poison managed to inject his formula into his son, who became Lazarus. This child, condemned to immortality, returned to Argentina in 1995, carrying the fever in his body, forcing him to undergo constant transplants. Now, he seeks the heirs of the lodge to recreate his ancestors' formula.
