Hello Down There

A scientist (Tony Randall) and his family are chosen to be the first family ever to live underwater, in a specially-made glass dwelling. But as he and his wife (Janet Leigh) and their two children prepare to move, their daughter (Kay Cole) insists on bringing her boyfriend (Lou Wagner) who is a rock star wannabe. The end result is the girl and the boyfriend form a kind of underwater rock band with her little brother (Gary Tigerman)on drums. Cute, silly songs get sung. Danger rears its ugly head with a possibility that the family will be eaten by sharks.
