Family travel is never easy, but family time travel is the worst.
When the four Robinson brothers, Fred, the astrophysicist, Ernie, the martyr, Jack, the jokester, and Will, the peacekeeper, along with their wives and children, are pulled back into Northern Nevada's gambling and mining past, they will have to learn how to set aside their issues with each other to get back home.
But whatever their family problems are, they will need to resolve them fast because a rouge member of the Observation Council isn't adhering to the 'observation' part of the council.
And if he figures out how to steal the Robinsons' time technology before they can get home, the Robinsons will find themselves lost in the past forever.
