"Confederate soldiers led by Vance Reno (Richard Egan) rob a Union train of its payroll money. But because the Civil War officially ended the day before, their theft was not a legitimate act of war. Now an outlaw, Vance takes his share and heads home, where he intends to marry his fiancée, Cathy (Debra Paget). But upon arrival he discovers that she has already married his youngest brother, Clint (Elvis Presley). The troubled family tries to reconnect -- while also evading the law. A young man, Vince Everett (Elvis Presley), is convicted of manslaughter after being drawn into a bar fight while trying to defend a woman. In prison, Everett finds salvation when his cellmate, a country singer named Hunk Houghton (Mickey Shaughnessy), hears him sing and pegs him as a future star. Once released, Everett gets a job in a night club and meets Peggy Van Alden (Judy Tyler), a young woman who works for a record company and who, like Houghton, also sees talent in Everett. All musically gifted race-driver Lucky Jackson (Elvis Presley) wants in Las Vegas is to score enough money for a new car motor so he can win the Grand Prix. When he encounters sexy swimming instructor Rusty (Ann-Margret), he considers staying around longer. After Lucky loses his winnings in the hotel pool, he's forced to remain in Vegas long enough to win back his dough -- but now he also wants to win the Rusty's heart. Unfortunately, so does his slick racing enemy, Elmo (Cesare Danova). Delivery man Deke Rivers is discovered by, and recruited to join a country and western band. However, Deke's road to stardom is complicated by a romantic dilemma involving the band's publicist and singer. Among the many musical highlights are `Teddy Bear' and `Lonesome Cowboy'."
