When the Kwimper family car runs out of gas on a new Florida highway and an officous state supervisor tries to run them off, Pop Kwimper digs in his heels and decides to do a little homesteading. He and his son Toby and their adopted children - Holly, Ariadne and the twins - start their own little community along a strip of the roadside. The fishing is good and the living is easy until the mob sets up a gambling operation and the state supervisor sics a sexy social worker on the Kwimpers in an effort to take away Ariadne and the twins.
