Sketching a plot

I went to my shrink and told him that I had an issue with plotting, and then, suddenly, as I was talking I began to see that indeed I had a plot in a rough way:

1. The President (Rigoberto, or Aniv de la Rev or whatever)
2. War on drugs
3. The President's daughter (Ana) is abducted
4. The kidnappers want the president to tell the truth
5. The president does not tell the truth
6. The kidnappers release the daughter who will hate her father from now on and tell the world the truth about him.

And I have a plot for a second novel:

1. A college teacher (Tania) is seduced by a student (Leonardo), who is 15 years younger
2. He moves to her house
3. She is crazy and his life becomes unbearable
4. He runs away

Maybe I can find a way of merging both stories. What if Ana was Tania's student, and Leonardo's classmate? And Leonardo--a progressive-minded student-- becomes a scapegoat of the Mexican corrupt police: they make him testify that he is a member of the gang who abducted Ana.

Tania teaches politics, and there are discussions among her students about the government. Tania is conservative, catholic, and a status-quo supporter. She tries to avoid that her students criticize the government in her class. But they continue arguing after class.

And what about the gang that really abducted Ana? Where do they come from? Who finances them? What is their ideology? What is their main goal?

To go on with the novel, they must be idealists, very uncommon people who have nothing to loose. But that is not part of the plot: I can find later a good reason for them doing what they do.
