They were time travelers, in real life, the main character commit suicide in his cabin playing russian roulette, or that was the urban leggend, in the series the young boy was dressed with horizontal white-red stripes shirt, and the main character witn a leather vest, they had a old watch like device wich told’em if the history was right (green light) or they have to fix it (red light) in order to return to the “present” of the young boy (when red light became green, the hostory was fixed), for example, in one episode, they “must” sink the titanic so the history was right and do not alterate the future-present, in other episode, they must help Edison to invent the lamp bulb, and the kid helped Edison giving him a straw of his shirt, hope can help me, with the name of the series or the name of the main characters, thanx.
