Overview: The pilot episode tells the audience the names of the characters of the programme, including the Gog family clan and their main antagonist Ray the T-Rex, in the form of cave paintings. At the beginning of the episode, the Gog clan are huddled together at night on a cold, bleak, windswept landscape. The Gogs are getting up to their usual revolting, uncivilized activities and hitting each other. A freak storm breaks out, terrifying them all, except the crazy infant, Girj, who finds it all amusing, causing the mother Ogla to kick Girj off screen. The storm causes a withered tree to be hit by a bolt of lightning which then sets it on fire, giving the Gogs the inspiration to make fire for the first time. Dim-witted teenage caveman Ogo quickly and unexpectedly turns to scream right at the camera as his hand is burnt by putting it into the fire. As he screams, grandfather Gogas hits Ogo over he head with his club, and the clan go to sleep around the warmth of the fire. They awaken sleepily to a hungry T-Rex named Ray descending on them, and as the Gogs scream and flee they leave behind the teenage daughter, Igi, who is almost eaten. Ogo saves the day when he holds a flaming torch to Ray's private parts, causing Ray to dart off quickly in pain. As Ogo basks in his clan's praise, he quickly loses it again as he blows the flame out, which was the last remnant of the fire they had, and as such the secret of fire is lost. The rest of the clan beat up Ogo for this, and the next night they remain cold without fire like the night before.
