Star Trek: The Motion Picture - Echoes #1

When a space anomaly thrusts a bounty hunter and her target-a criminal mastermind-into their universe, it's up to Kirk and his crew to stop them from unintentionally starting a war with the Romulans and unleashing a superweapon of foreign tech onto the system. But the strangers from another universe are more familiar than they assume for underneath their helmets are their doppelgangers from an alternate reality!
