is there any way to get that old file?

File contains critical information which is required by management.

If you don’t have any backup, you are out od luck and there is no other option how to restore it.

EDIT:
But if you have backup of database containing the site collection with the document you can:

1. Restore the database to some SQL server
2. Use unattached content database approach (PowerShell or UI)
3. Restore the file you need

How to do unattached content databse restor see documentation on TechNet https://technet.microsoft.com/cs-cz/library/hh269602.aspx
