Audience Member Liked this tv pilot involving secret service agents. Agent Diamondhead thwarts a plot by enemy agent Tree to steal a dangerous biological weapon from American hands with help from Zulu and Dragon Lady. NBC green-lighted "Grandpa Goes to Washington" over this highlighting a dismal period where the network was dominated by ABC in the ratings war.
