The film entitled Millions is about the life and adventures of Damian. Damian is a seven years old at the time. He lives with his family. After his mother dies, his father decides that they relocate to the outskirts of the city. While travelling, Damian finds a bag of money fall from a passing train. Damian calls his brother Anthony and shows him the money.
Anthony who is very selfish, wants to keep all the money to himself. Damian however believes as a Christian, he should be able to share with others. Based on a lecture he once heard about giving, he decides to give his money to the poor.
Some days later Damian learns in school that there will be a transition from using the pound to the euro. He realizes that his money in pounds will soon have no value. He drops a huge sum of money in the school's donation box. Dorothy who was collecting the money reports Damian's act to the principal. The principal calls Damian and Anthony for questioning. Anthony lies that they had stolen the money.
Some days later, Anthony's friend tells him about the robbery of a train. The train was loaded with money that had to be destroyed after the conversion from pounds to euro. Robbers invaded the train, throwing the money through the window at different locations as the train drove off. The robbers were planning to pick up the bags of money later. Anthony and Damian then realized the money they picked was stolen money.
One day a stranger comes looking around the train tracks. He asks Anthony if he has some money and Anthony accepts. Anthony later realizes he is one of the robbers. He gives him some money and tells him where to find Damian and collect more.
Before the robber gets to the house, Damian had told his father about the money and they had just left for shopping.
