Black Jack (TV) - episode 38 - 07 Aug, 2005

Sharaku, his sister, Black Jack, and Pinoco take a trip to a dig site where Sharaku's father works. They had uncovered ancient ruins. Sharaku's father had called for Black Jack, saying that he felt "Compelled to do so." That night, Sharaku takes a staff that was recovered from the dig site and heads deep into the ruins, tailed by Black Jack, Pinoco, and Watou. A monk who was waiting for them in the ruins is mysteriously injured, with several foreign bodies appearing in his body. Sharaku, seemingly possessed, compels Black Jack to save the man. Black Jack is then guided deeper into the ruins where a group of aliens had been hiding. The aliens had been shot at by humans, their medical equipment was destroyed and one of them was in critical condition. The aliens eventually convince Black Jack to start the operation by using telepathy to show him a picture of his mother. In the end, Black Jack and the others agree to keep the whole ordeal a secret.
