Plot

A young boy with a gift for technology accidentally creates two doubles of himself. The three of them work together to help their injured maid finish her work and then fight the school bullies.

Twelve year old Pavel's (Pavel Divis) mother (Lenka Termerova) is a scientist who is working on a project that turns matter into exact copies of nearby animals. Since Pavel is a technology whiz he would like to perform experiments on the matter, but his mother will not allow it. One day at school Pavel is confronted by the school's three older bullies (Martin Wimmer, Jiri Sandera, Jiri Petr). He skips the rest of the school day and sneaks into the laboratory where his mother works in order to steal some of the matter. He experiments on the matter but only manages to disrupt the electricity in his apartment building. Hearing his mother come home from work, Pavel splits the matter in two and hides half of it in his bed. That night a storm occurs and he wakes up the next morning with a copy of himself (Lubos Divis) in his bed. Later, he goes to a beach with some school mates and takes the other half of the matter with him. While there, another storm turns the second half of the matter into a second copy (also Lubos Divis). Pavel takes the second copy home to meet the first copy. At first, the two copies do not get along, but eventually the three Pavels begin to work together to clean the apartment, cook dinner, help their injured neighbor (Blazena Holisova) and later fight the three bullies.

Twelve year old Pavel's mother is a scientist who is working on a project that turns matter into exact copies of nearby animals. The copy inherits the characteristics of the original animal's personality and feelings as they were at the time of the copy. Since Pavel is a technology whiz, he would like to perform experiments on the matter, but his mother will not allow it. Pavel gets in trouble in school one day, which leads to one of his friends also getting in trouble. Later that day, he is confronted by the school's three older bullies who force him to destroy another boy's soccer ball. He skips the rest of the school day and sneaks into the laboratory where his mother works in order to steal some of the matter. When he gets home his experiments only manage to disrupt the electricity in his apartment building. While his mother is on her way home from work, the teacher, the friend's parents and the neighbors all complain to her about Pavel's behavior. Hearing his mother come home, Pavel splits the matter and hides half of it in his bed. His mother tries to punish him for his behavior, but Pavel promises to be better. He goes to bed, but that night a storm occurs. He wakes up with a copy of himself in his bed. Since Pavel's feelings at the time of the copy were to be better, the copy is a good boy. Pavel sends his copy to school, where he also encounters the school bullies. Later Pavel goes to the beach with several of his school mates but some of the girls throw the boys' clothes into the water. This angers Pavel and he chases after them. When Pavel gets his clothes back, he pulls the other half of the matter out of a pocket and buries it for safe-keeping. But his friend wants to know what it is and Pavel yells at him. A storm blows in which causes everyone to run. Pavel goes to retrieve the buried matter, but is surprised to find a second copy of himself. Since Pavel was angry when this copy was made, the second copy is angry. Eventually they make their way home where the second copy meets the first copy. The two copies do not like each other since their personalities are different. The next morning, Pavel locks the first copy in a closet and lets the second copy go to school. But he also encounters the three bullies. The three Pavels begin to work together to clean the apartment, cook dinner, help their injured neighbor and then fight the three bullies. The three bullies are left bloodied so their parents take them to Pavel's apartment to confront his mother about her three sons. She assures them she only has one son and calls Pavel out of his room. All three bullies identify Pavel as the person who beat them up, but their parents do not believe them since they think there is only one Pavel and he is so much smaller than they are. They grab the three boys and march them out. Pavel's mother does not understand what has happened, so Pavel wants to show her the two copies. But when they go back to Pavel's room, the copies have changed themselves back into matter.
