Developed thriller idea.

The woman is cooking in the kitchen. She's cutting vegetables with a big sharp knife on the cutting board and throwing them on the hot pan. The nice music is playing from the radio, she is quietly singing along.

e.g. "You make me crazy" by Gnarls Barkley
  

      Woman is wearing a dress (fashion of 50^th) and apron, her hair is tied up, we can also notice a ring on her figure – she looks like a typical housewife. However, she has a fresh scar on her cheek and a couple of bruises on her hands, which are not identified from the first look. 

Suddenly, we can hear something else apart from the music, some sound like mumbling, but very quietly. She is ignoring the sound, still cooking. It repeats. The woman looks a bit irritated and enhances the volume of the radio. She keeps on cutting vegetables, which sizzle reaching the pan. The sound repeats again, now louder. She tries to increase the volume of the radio again, but its’ on maximum. The sound repeats. She leaves the vegetables and expires to calm herself down. She turns off the radio. Now we can hear exactly what kind of sound is that – it’s the human trying to scream with the taped mouth. She wipes her hands and knife with the towel and puts it on her shoulder. She then walks around the table with the knife in her hand.

 On the other side, on the floor there is a bounded man with a tape on his mouth, making that sound. We see a ring on his finger. We realize they are married. He looks at her, frightened. She looks irritated with him. The woman bends towards him and points her knife at his chin, lifting his head up. He obeys. She smiles at him creepily and says: “You’re making too much noise, darling. I can’t cook”. He looks at the knife, back at her, silent. She swings her hand and cuts his cheek. The blood flows down his face. “That’s better. Now we look similar, my love”. 

She stands up and walks back to the cutting board and turns on the radio again with the same song. She starts singing along quietly and quite cheerfully. 
We then see that man, he looks pale and frightened. The camera slides down his body showing his t-shirt wet with blood at the side of his belly. Blood drops fall down on the tile. He looks at it. We realize it hurts.

She then takes a human liver out of the bowl nearby her, puts it on the cutting board and starts to carve it. The man bends round the table and sees her throwing meat pieces on the pan - he notices the liver. We see his facial expressions when he suddenly realizes she’s a cannibal – he bends back, closes his eyes, the sweat is running from his forehead, his loud mumbling is hardly heard through the radio and the sound of the knife beating the cutting board. The woman takes a liver cut in pieces and puts it in the pan, smiling. It starts to sizzle in the oil.

         

The whole film: The main hero – is a typical obedient housewife, a victim of domestic violence and oppression of all sorts from men. Due to serious health problems in the past she is not capable of having children now, which is the reason her husband does not treat her like a proper woman. She was often subjected to violence, what drove her crazy in the end. Now she decided to have her revenge over all men who treated her awfully, by doing what she ‘was born to do’ – cooking. The story-line is telling us about her inner fragile world and how she ended up in such an awful state, as murderer and cannibal, from her perspective.
