Koroshi is actually a compilation of two Secret Agent episodes, Koroshi and Shinda Shima. In the last season it was decided that the episodes would be made in color. Unfortunately, Patrick McGoohan grew tired of the role and quit with only two episodes being made. Koroshi deals with an ancient death society based in Tokyo which plans to execute world leaders. Drake travels to Japan in order to seek out and destroy the organization. Shinda Shima deals with an island which is supposedly and evil one but contains a base in which the society conducts their affairs. Drake helps to overtake the island give it back to its people. Both episodes are action filled yet they lack the witty dialogue and character development of previous Secret Agent shows.
