OP, I don't say this often to people, but right now, you have virtually no chance of an acceptance at any MD or DO school in the country. Your extreme DOWNWARD trend from CC to UCLA is a huge red flag, and your UCLA GPA is unacceptably low for any medical school in the United States. Your plagiarism incident, based on the way you described it, is something that can be overcome, but your academic credentials at the moment is terrible.
If you truly want medical school, you need to demonstrate, at minimum, two years of strong academic performance (particularly in the sciences) at a four-year institute. A formal, reputable, post-bacc is probably the most ideal path for you, but often times, these programs are competitive to get into, and again, your current academic record is going to be a roadblock.
If you cannot get into a formal post-bacc program, the next best option is to take individual science courses (prereqs and upper-levels) on your own at local universities. If UCLA is too expensive, you can take courses at Cal State Universities, which offer plenty of rigorous, upper-division science courses.
Before you should even think about medical school applications, you'll want to demonstrate at least 2 years of academic success (3.6+ GPA) through post-bacc studies. You'll also have to retake the new 2015 MCAT and continue working on your ECs. Finally, you'll have to explain and overcome your plagiarism IA, which is very doable.
In short, it is possible for you to become a doctor, but be prepared to work your butt off for the next 2-3 years. Good luck.
