Kelly (Kelly Clarkson) and her best friends Kaya (Anika Noni Rose) and Alexa (Katherine Bailess) leave Texas to have some fun in the Florida sun. Making their way to the same destination are college students Justin (Justin Guarini), Brandon (Greg Siff) and Eddie (Brian Dietzen). Kelly's friends are drawn into the beachside fun, while Kelly tentatively navigates a sea of strangers. When her eyes meet Justin's, everything changes, in as instant. The feeling is mutual and Justin's on fire. But as luck would have it, he loses Kelly's number -- and boy-crazy Alexa has already set her sights on Justin. She will stop at nothing -- even betraying a friend -- to nab Justin as her own.
