Comedy, mystery and mayhem combine when Elvis Presley plays Guy in Double Trouble, a romp involving stolen gems, trenchcoated defectives - that is, detectives! - and more. Through it all, a guy's gotta do what a guy's gotta do. That means performing a tune array including the title tune, City By Night, Could I Fall in Love?, Long-Legged Girl and There's So Much World to See. Trouble was never this cool and this much fun.
