The film is about Ruby, a killer played by Jean Renault, who embarks on the road to revenge for his lover who was killed by an enemy. During this time, he meets Quentin, who is kind and warm-hearted and a little stupid, and the two have a ridiculous period of French comedy.

Steel egg is a big talker, chat with people regardless of time, occasion and object, and therefore he has no friends, in prison one by one to change roommates, until he meets the killer Ruby who always does not speak, steel egg can always speak to Ruby, Ruby does not speak, nor is he angry, the brain is always planning to escape, although Ruby's prison escape plan is seamless, but do not want to be stuck by the steel egg, but also because of the help of the steel egg, the two escaped in the chaos, Ruby still has a plan to avenge his girlfriend, However, Iron Egg just wants to be friends with Ruby forever, open a restaurant, one chatters, one shouts to the other to shut up, and the two people are on the way to escape, clashing and laughing.
At the beginning of the movie, it is the steel egg robbing the bank, in the process of the robbery, the steel egg enters a movie theater, which is showing cartoons, the child laughs together, his huge head is also sandwiched between the children, the smile is thick on the face of a flower, when the police find him and take him away, he still has to struggle to look twice, how can there be such a childlike stupid thief.
After the steel egg arrived at the prison, he successfully made all the prisoners in the same room as him collapse, his words were many and miscellaneous, and every person opened with "Hello, I am a steel egg, a Montage", expressing a strong desire, although he himself had no malice, but he was always able to ignite the anger of others, and pounced on him with a snort, and the partial steel egg was big and strong like a cow, so it was often carried out by others.
The warden was furious, the steel egg had driven five prisoners crazy in two weeks, and he must get him out, so he invited the doctor of the prison's mental hospital, an expert on kindness and good intentions, to do a psychiatric evaluation for the steel egg.
The poor old expert collapsed at the hands of the steel egg again, and he said that he could not accept the steel egg to the mental hospital under any circumstances, because there was no problem with the spirit of the steel egg, and the prison director pleaded again and again, and the psychiatrist firmly refused, saying that we were a madhouse, not a stupid hospital.
Jean Renault is on the scene, yes, the killer in the killer, here he is still a sharp-handed killer named Ruby, with a cold temperament and never cooperating with people. Ruby went to prison, did not say a word, refused to disclose anything, the police wanted him to open his mouth, sacrificed the steel egg this trick, the steel egg nagged and said, but Ruby was cold, did not respond at all, the steel egg beat the heart of the rupee, hope to be able to escape with the rupee, partner to open a tavern, the name is well thought out, called "two friends home".
Ruby commits suicide, Steel Egg commits suicide, Ruby goes to an insane asylum, and Steel Egg also strongly demands to enter a madhouse. He just wanted to be with his heart's partner. After Ruby committed suicide, he sat there dumbfounded, helpless in his eyes, like a lost big kid. Hearing that Ruby was going to be sent to a mental institution, he anxiously said to the doctor, "I am also a silent person who never speaks, if it were not for you, I would never open my mouth", and struggled to prove that he was also a mental illness.
They escaped from prison together, the steel eggs kept causing trouble along the way, Ruby collapsed and went crazy countless times, but could not get rid of him, Lu bi first suspected that he was a policeman, and then became suspicious, extremely confused and asked him, who are you?
The steel egg opened his innocent bull's eye and said, I am the steel egg, the steel egg of Montaki! Only to do and run into trouble, some trouble, some jokes, and some small touches. Ruby turned himself in, saying he would give him a sum of money and that he would be able to open a tavern when he got out of prison. The steel egg licked the jam-like digestive medicine on his finger and said, I can't ask for it, the name of the tavern is two friends' house.
RUBY: But how can you think I'm your friend? Steel Egg looked up in amazement, his unkempt hair, stared at Ruby with his signature innocent eyes, and said in surprise: Aren't you my friend? Then continue licking the digestive pills. Ruby finally gave up communicating with him and said viciously, "Don't eat, you'll have diarrhea." "In fact, before this, Ruby's heart should have melted." The soundtrack of the film is light and cute, and the ending song is light-paced, and the occasional "Tais-toi" sounds. If you want to laugh so hard one day that even the haze seems to show the sun, and in addition to laughing, your heart will be touched fiercely.
In fact, the most intelligent people often have a pure heart, and the most innocent people often have wisdom that ordinary people do not have. The killer Ruby should have been ruthless because he was the killer, but he was actually the most loving, as can be seen from the fact that he has been taking care of the egg and is sad because the egg is injured. Gang Egg is the stupidest person in the world in the eyes of others, but in the process of absconding with Rupee, he saved the killer Rupee many times. The big wisdom of the gang egg is 'goodness', he keeps telling Ruby not to kill, don't kill, always talking about how the bar the two of them are going to open, he is actually influencing a cold and vengeful killer, so that the killer Ruby has a vision of the future.
The steel egg has not been able to stop mouthing, some have not been saying, making people bored and speechless, but what is this because? Just because he has no friends, no friends who can really make friends with him. So when he met the killer Ruby, as usual, he kept talking to Ruby, but Ruby did not reply a word, not so much as not to say that there was no reply, but to say that there was no scolding or nagging. At this time, gang egg felt that he had finally found his only friend, a friend who could listen to him. So he has been with Ruby, no matter what Ruby says about him, he stays by Ruby's side, when Rupee encounters danger, he saves him, when Ruby is injured, he heals him, he is so determined, whether his friend is a killer or not, whether his friend wants to escape from prison, no matter if his friend cuts his wrist, he follows suit, just to be with his friend Ruby.
The end of the film is not exhausted, the final ending is up to you to imagine, but the picture is clearly displayed in front of you: the 'two good friends bar' just made sandwiches at the bar, Ruby chatted with the guests at the cash register, they looked at each other, smiling...........
