In "Gavilan," Robert Urich is an ex-CIA agent who gets involved in high adventure and underwater hi-jinks as an oceanographer with a laser-equipped mini-submarine.
Robert Gavilan is an idealist in a hard world, which is why he's an ex-agent. He hates violence and says he "couldn't tell the good guys from bad guys." Tonight he risks his life for a scientist whose book was inspirational to him. After rescuing Sarah Snow, a colleague, from guerrillas in Africa, Gavilan learns that the lady's husband, a renown scientist, is still held captive by the terrorists. Sarah pleads Gavilan to return and attempt a rescue.
