Your Face or Mine? (2010)

Carter must take the bi-annual D.O.D. re-certification test in order to remain sheriff of Eureka. The test takes 48 hours and the test is conducted completely isolated from the rest of the town. Jo fills in as active sheriff while Carter is taking the test, as well as taking care of Zoe while Carter is otherwise occupied. Allison wants to put a new security measure into effect that uses a DNA scan to grant or deny access to various points of Global Dynamics. Henry doesn’t want to install the new devices, so Jo is called in as the deciding vote. Jo decides to have the devices installed and is the first one scanned for identification, but the device malfunctions and nearly electrocutes her. When Jo comes to it is discovered that someone had stolen a critical piece of the device. Allison wants to pull Carter out of his test to have him help find the thief, but Jo insists that she can track down the thief herself. When Jo asks Henry about the missing piece of equipment, he tells her that he is also missing an important piece of equipment. Leaving Henry to ponder a possible link between the two stolen items, Jo heads for the Smart House to help Zoe with homework. Jo finds that walking a mile in Carter's shoes is proving to be a challenge, especially when Zoe wants to blow off work and go to karaoke night at Café Diem. Jo's still feeling the effects of her near-electrocution and forbids it, wanting nothing more than to sleep. Zoe uses this as an opportunity Zoe to sneak out. Jo soon catches Zoe performing at the Café. Yet instead of grounding her, Jo joins in the fun, drinking too much as she sings and flirts with Fargo. Jo ends up kissing Fargo just as Zane enters the Café. Jo insists that she's fine, but Allison and Henry worry about Jo's state of mind after she begins behaving more erratically. A third theft then occurs and the DNA scanner identifies Jo as the thief. Only Jo knows that someone is stealing her identity, gene by gene. Trapped in that person's body, Jo has to convince a skeptical Zane of her true identity.
