'Old vehicles, a policeman on a bike and now a 1957 telephone directory! What was going on? ...As he walked out into the daylight his mind was in total confusion ...It was beginning to dawn on Brian that he had travelled back in time!'

Soon he is swept up in a whirlwind of non-stop action and catapulted into the front line of a battle to save the world from alien domination.
