Jessica (Angela Lansbury) accepts the invitation of her niece Carrie (Kate McNeil), the wife of astronomer Leonard Palmer (Dean Jones), to be on hand for the return of a long-lost comet. Thrilled at the prospect of witnessing this stellar phenomenon, Leonard takes a long look through his telescope -- but doesn't like what he sees. Soon thereafter, Carrie's ex-boyfriend, business executive Drake Eaton (Steven Ford), turns up murdered...and Leonard is the prime suspect. ~ Hal Erickson, All Movie Guide
