The movie The Debt can be seen as being both implicit and explicit in its ideology. There are moments where the story seems to be told without a particular slant, but I believe the movie's true ideology is explicit. The audience is told the story of three agents through the use of flashbacks. The agents (Stephen, David, and Rachel) were supposed to kidnap Dieter Vogel and bring him back to Israel for a trial because of his atrocious actions against the Jews during WWII. They kidnap him, but are unable to leave at their assigned time. Eventually, Voge lescapes, but the agents all agree that they will tell the world that Rachel killed him. They figure that he will never show his face again so their story will be safe. Yet, David is not really happy with this decision because he wants Vogel to stand a fair trial and not to be thought of as dead. This is where the explicit ideology comes.
In the scene where David visits Rachel when they are older after her interview, he explains that he has been traveling for years just looking for Vogel. Rachel asks him why he has continued to search, but David tells her that he wants to bring Vogel in for justice and then tell a journalist the true story. Rachel tells him that she doesn't agree because she has to look out for her daughter. David is representing the movie's real ideology--you should always tell the truth even if it will hurt you. David's viewpoint is there to persuade the audience that it is morally right and the only true course of action for the characters to take.
The second scene of explicit ideology comes at the end when Rachel is at the hospital to kill Vogel. She writes a note to a journalist explaining what really happened over thirty years before on their mission. This scene is meant to show that the morally right thing to do has finally been done. The truth is going to be told to the world and justice will be carried out. Rachel has made a decision that will hurt her daughter and herself, but she knows it is still the right thing to do.
