The only thing interesting about this script is the title.
1: Your wife does not come down for breakfast and tell you to get to work because you need money for the mortgage without so much as saying good morning.
2: Your boss does not fire you on the spot without so much as a verbal or written warning.
3: You do not walk around in the middle of the day to find a mixed martial arts event taking place in a warehouse with the back door open.
4: If you did happen to find this going on, I seriously doubt they would let random passers by jump in the cage and fight in their shirts and ties.
5: They would certainly not give you $1000 for it.
6: I'm quite certain that your main character was not important enough for Tony to go to the trouble of kidnapping his family.
7: I sure I could find more problems with this script if I read it again.
Whilst this script is poor in every sense of the word, the idea is not bad. Mixed martial arts is becoming extremely popular through organisations such as UFC and PRIDE. You could write a "Rocky" styled script where your main character faces hardship throughout his life and tries to make it as an ultimate fighter? Just an idea but you must find originality, and please; do not allow your main character to come home in the middle of the afternoon to find his family kidnapped with a note saying "fight, or else".
All the best,
