The underwater clan includes his water-phobic wife and his daughter and son, who are part of a rock and roll band. They bring along the lead singer and drummer. Along the way, they have to contend with a competing engineer who promises to mine the ocean floor for the businessman. A record producer likes their music and books them on TV, leading the kids to try to escape to the surface.。
