Karel Novak is an incredibly naive Czech immigrant who is taken under the wing of streetwise New York chorus girl Sylvia. With the help of lovable cop-on-the-beat Murphy, Sylvia hides Karel from the immigration authorities and ultimately falls in love with him. In addition to Karel's illegal-alien status, the plot is complicated by a crooked lawyer and a group of well-meaning welfare workers who endeavor to place Sylvia's kid brother Frank in a foster home.
