Sarah Booth Delaney and her friends can't help falling in love with Christmas this year, which they plan to spend celebrating the King of Rock n' Roll at the annual Elvis Festival in Tupelo. The main attraction is an Elvis impersonator competition, drawing impersonators from all over the world to honor the king.

But before the revelry can get underway, a priceless jewel-encrusted replica of a belt once worn by Elvis is stolen from its display case, and Sarah Booth and Tinkie are roped into one of the biggest heists in the history of Mississippi. Soon suspicious minds are lurking around every corner, with one eyewitness even claiming to have seen Colonel Tom Parker, Elvis's long deceased and highly questionable manager, prowling around the festivities. Sarah Booth will have to find the devil in disguise or she might just end up singing Jailhouse Rock herself.
