Rush of Fear (2003)

Synopsis
Joseph Kell and Rosanna Arquette star in this film as Jack and Alex, a married couple trying to work through a rough spot by taking a vacation to a small seaside town. Springs of hope turn to rushes of adrenaline, however, when Jack is kidnapped while exchanging their rental car, which apparently contained a rare stolen diamond. Finding no help from the police, who accuse Jack himself of foul play, Alex turns to one of her husband's clients, Bryant (Chris Potter), and together, they try to negotiate Jack's return. ~ Cammila Albertson, All Movie Guide
