Michael Clifford, is a full-time agent working with the CIA. Growing up, the male only watched action movies and it was his dream to become an undercover agent, but due to his mental health, every agency he signed up with would shoot him down. Up until the day of his twenty first birthday, Michael had a normal life - a five-year-old daughter, Kiley, who he raised on his own, a good job, a large home, friends, family, anything he would need in life to be perfectly content, but that's when he got the call that he was wanted to go into training immediately and then go undercover. He almost didn't take the job - he figured that his life was planned out for him, but after being convinced by his mother, he took the job and she took Kiley. Kiley and his mother are the only ones who know about Michael's undercover work - even they shouldn't have known about it, but he couldn't just up and leave without an explanation, especially not his daughter, his world. After training, they immediately sent him off to Italy and then Paris, and then Rome and then back home to Australia, and then to another place, and another after that. After about two years of working with the CIA and the same partner for those two years, his partner, who always stayed in the basement of the CIA to help him with missions and undercover work, was let go from the CIA and Michael was granted another partner - this one going by the name of Luke Hemmings, a lanky boy, just coming out of college for computer technology, with the biggest, most beautiful eyes Michael had ever seen, and a voice that could create world peace. Michael fell in love with the sound of that boy's voice.
