30 Years to Life (1998)

In the near future, instead of being sent to prison criminals are aged for the number of years the system feels is adequate to the crime they committed. Vincent Dawson is a 15 year old, whose late father was a musician who didn't exactly make it and died tragically. Vinnie hopes to be a musician too but his step-father is not very supportive, and when they have a violent argument, his step-father is killed and he is the prime suspect and evidence is found against him. He is sentenced to be aged 30 years. Now, as a 15 year old trapped in a 45 year old body, he sets to prove his innocence and hopefully the procedure could be reversed.
