A group of young activists abduct a senior politician and use a psychological mind game to extract a murder confession but he turns the game around, insisting he has proof that one of them is a government agent.

Thanks, Karel. Much appreciated.

"A group of young activists abduct a senior politician and use a psychological mind game to extract a murder confession as part of a clever scheme to extort millions but he turns the game around by convincing them that there's a traitor in their ranks and the proof is in a security briefcase along with the millions in his safe deposit box".

Start with the inciting incident:

"When a group of young activists abduct a senior politician, and ... murder confession"

Then you'll see that there is a lack of story material for Act 2: all we have here is that "he insists he has proof that one of them is a government agent".

In other words, this logline is super heavy towards the setup, but doesn't promise much after that.
