Gov. Gatling is being urged by his aide, Taylor, to favor the passage of a bill authorizing a power project that may destroy a river and its ecological system. However, the Governor has some serious doubts about the matter. He will give his approval only because the state needs the energy source and there appears to be no alternative. During the night, a pile of dead fish mysteriously appears in the gubernatorial mansion. A note says that these fish were killed by a power project, and if the new dam is built, the results will be the same. The note is signed "El Gato" -- The Cat. The Governor cancels a press conference and decides to reconsider the situation. Security chief Ackerman investigates, but El Gato strikes again, this time with a truckload of river bottom sludge. Taylor is furious, but Marcy, the Governor's secretary, sympathizes with the romantic environmentalist. Ackerman suspects everyone, and the staffers are outraged to learn that he has them under surveillance. El Gato strikes once again, filling the Governor's office with soap suds to simulate industrial pollution. Late at night, Benson catches El Gato, taped and masked, in the kitchen. He easily subdues the man, but is moved by his sincerity and harmlessness. El Gato is very persuasive, particularly when he kisses Marcy. The masked man has an alternative energy plan, which he is eager to present to the governor. Benson hides El Gato from Ackerman and agrees to set up a meeting with the governor. Over Taylor's objections, the governor agrees to hear El Gato's plan, which is to be presented by a "well qualified spokesman." This turns out to be Katie's science teacher, a clumsy, bookish individual whom Benson recognizes as El Gato unmasked. His plan is a good one and the governor is relieved to find a way to save the river. Marcy is, still fascinated by her memory of the masked man, and Benson is relieved to know that there will be no more unpleasant messes. © 1980 Witt/Thomas/Harris Productions. All Rights Reserved.
