Frank (bill murray) is a well-behaved city zoo who lives with his daughter Nisha. One day, greedy, he accidentally ate an egg contaminated by monkey saliva, and the camera followed the egg to his throat and stomach ... So our story began-in Frank's body, more accurately, in his blood, there was a kind of white blood cell called Oz (voice: chris rock). Like all white blood cells, Oz's job is to patrol the blood every day to deal with those who dare to disturb the human body. Although shouldering such a difficult task, Oz is not a person who follows the rules. No, it should be said that he is not a clever white blood cell. He is a born vagabond, and he is the most resistant to rules and regulations. He likes to prove that he is a unique "personality" cell.
Perhaps in order to restrain him, Oz's boss sent him a new partner-Drax, a new type of cold medicine tablets specially scripted. This Drax comes from a pill that Frank swallowed because of a sore throat (voice: david hyde pierce). He is an excellent agent who comes from a prestigious school and follows the rules. Then, these two guys with completely different sexual habits got together and formed an investigation team. Of course, they had quarrels and quarrels. Just as they were at loggerheads, a dangerous virus, Shrek (voice: Lawrence Sherbone), brought by the eggs eaten by Frank, began to gang up in Frank's body, bullying and overbearing, trying to take away the core element of Frank's life-DNA. In order to fulfill their sacred duty as a white blood cell, Oz and Drex finally put aside their prejudices and joined hands against foreign enemies.
At the same time, Frank finally fainted to the ground due to physical discomfort and was taken to the hospital. The doctor tried to find out why Frank was ill, but Frank became weaker and weaker. Nisha rushed to the hospital and cried in front of her unconscious father. .
Just when Frank was dying, the fight between Oz and Shrek shifted to Nisha's false eyelashes. However, the heinous Shrek was defeated by Oz. Oz grabbed the DNA and went back to Frank, saving Frank's life and becoming a hero in Frank City. Shrek was buried in alcohol.
