Lizbeth Mendoza, works for the UCSA (Under Cover Spy Agency). Lizbeth and her friend, Yvette, work on the computer, searching for locations, tracking, and getting information, nothing big really. Until one day, one of the spies got injured, and Lizbeth's boss, Judith, assigns Lizbeth to be partners with Luke Hemmings. Finally, it's Lizbeth's chance to show that she can be out on the field.... Except her problems with her partner, show the opposite. They both don't really like each other and say mean stuff to each other, until time by time, it starts changing, and Angel, Luke Hemmings first partner, is all healed. Are Luke and Lizbeth falling in love? Or will Luke pick Angel? Or will Luke betray both of them?...
