While vacationing on a houseboat situated smack dab in the middle of a dry lake bed, the Stanton kids and their cousins discover a time machine that makes their lives a whole lot more interesting...and without a doubt more dangerous!

When the Stanton kids take a trip in the time machine into the year 3010, they meet up with a race of people called the Troikas who are intent on creating perfect human beings. Initially, the children are impressed with their abilities, but, after they realise that the Troikas aren't what they seem to be, they decide they better return to their time—fast. However, the Troikas have other plans. The children will need to employ every trick they can think of in order to escape. The year 3010 is not at all what they bargained for!
