Hi,
it is possible to recover your data if the database is in full revovery model. You have to perform
1. a transaction log backup
2. restore the most recent full backup with norecovery
3. restore all (if exist) transaction log backups with norecovery
4. restore the last transaction log with recovery using the STOPAT option if you know the exact time that the wrong query has been fired.
If the database is in simple recovery model it is not possible to recover your data.

-Do you have any backups available with you before the delete?
-What is the recovery model of your database?

If you are in simple recovery you can restore the last full backup to another database and then copy the deleted rows (if they exist in the last backup) to the source database. I have done this when I did not want the entire database to be unavailable during a restore.

No quick UNDO solution for sure
In additions to above methods (restore backup, find data)
you could perhaps use 3rd party tools to either
- read the trans. log for data
- use Red Gate Data Compare to compare Backup with Live DB, and sync. the missing data

The best way will be restore the backup in a different box that is taken before deletion of the data. And if you know the query that deleted the data then just modify the query such that it selects the same data instead of deleting. And then you can export that data from there to the prod.
