About the title
Three guys from a small town, looking for easy money, decide to rob the local bank. Armed with an excavator, they break into the vault and haul everything out. The morning after the heist, the robbers learn that 25 million rubles were stolen from the bank. That's when the question "Where's our money?" hangs in the air, because in reality the trio only took a million out of the bank — which means either there's a "rat" among the friends, or another 24 million is circulating somewhere in town.
