CI5: The New Professionals S01 E02 Phoenix

A professional hitman, the Phoenix, who had been believed to be eliminated in 1981, in an operation, which Malone was present at, appears to have returned from the dead to seek revenge on the men who were responsible for his "assassination". However, if the hitman runs to form, the operation to hunt down those who hunted him down may be a bluff, and the Phoenix may have another target.
