The Samurai (1962)

The Spider (8x10)

:

Kongō summons Hyōe the Spider, a ninja with special kills, and orders him to kill Shintarō. The Spider uses the lamp in Shintarō's room to light a fuse to bombs below the Sainenji. However, Tonbei smells burning and Shintarō realises it is coming from the lamp. He cuts the fuse. Outside Tonbei fights with a ninja and an old man is accidentally wounded. Tonbei, unaware this is the Spider in disguise, takes him inside where Shintarō tends him and sends for his daughter, Chika. She is a ninja, too, and blows a sleeping drug into the room where Shintarō and Tonbei lie while the Spider moves under the floor below. Shintarō who had covered his face with the futon stabs down and the Spider flees outside. Wounded with a shuriken in his shoulder he leaps into a tree where Shintarō tries to persuade him to come down and get medical help but he kills himself after reminding Chika of the ninja code.
