Thompson may be only seventeen but he knows he's just checked into Heartbreak Hotel for good, now that his girlfriend, Caroline, has put an end to their burning love. Since then he's been sleepwalking through his summer job at Super Kmart while desperately dreaming of ways to win her back. He even drops by the Tiki House on Elvis Presley Night hoping that she, a diehard fan of the "King of Rock 'n' Roll," will be there as well. That's when he meets Johnny Lee Young-real estate agent by day, Hawaii's Favorite Elvis Impersonator by night-and the lovesick teen's world suddenly takes a wild and unexpected turn. As luck would have it, Johnny needs a temporary assistant to help with equipment and social media and Thompson eagerly accepts the offer, hoping it will distract him from his painful and lingering romantic issues. But like Thompson, Johnny is nursing a secret heartbreak and pining for his own lost love. So the new roadie starts making plans-with a little help from his friends Ronnie and Greta-to accompany the counterfeit King on an odyssey of a lifetime that will take them far from their island paradise home in search of true love.
