After his son confesses a murder to him, an obsessively upright police officer on the brink of a once in a lifetime promotion must use all his power and skills to destroy all evidence before the truth is uncovered.

I think it could be better if in the logline you raise the question if the father will or not commit a crime to save his son instead of just give us the answer.

Thank you all for the feedback. As Nir and dpg said, this is a contradictory character who has to choose between the written law and the family law. But I think that my approch on the story is wrong. I really like dpg's idea that the MC discovers his son is involved in a crime and that solving that crime is intimately linked with his promotion and his future as a police officer. That would place the character right in the middle of his choice and would also put the story in motion. As Richiev said, there is no point in his son confessing the crime as it would also sound like an ad hoc information to the script and an easy way out of the problem. Once again, thanks a lot for your feedback. It's really helpful. Cheers.

If his son has confessed I am not sure what the point would be.

As for the rest I do get why a father might go against his nature in order to save his son.
