Hey Brandon took a look, a few thoughts, all just my opinion of course.
1) The scene headings either need a time element Day/Night or Continuous to indicate that they run on one into the next.
2) 'We see', use sparingly and see if you can write the scene without it. e,g,
We see Justine (25) a fit, overly optimistic woman doing dance moves.
could easily be
Justine (25) a fit, overly optimistic woman, dances enthusiastically in front of her class,
3) Characters shoud be capitalised the first time they are introduced in a script, e.g. IRA first time you show him.
There's a few examples of typos and odd sentence construction so worth a review.
The story itsef though was pretty decent, liked the building feeling of brooding and paranoia and Ira was well established.
The ending and transition to Justine's house threw me a little so may be worth looking at that
Good effort though.
