Cache Cash (1994)

When young Antoine (Aurélien Wiik) happens to spot criminals hiding the loot from a bank robbery, he decides to relocate the money, since he has little respect for thieves or adults. Along with his friend Lisa (Joséphine Serre), Antoine opts to spend some of the stash on a trip to a coastal town. Unfortunately, one of the robbers, the ruthless Max (Jean-Claude Dreyfus), will stop at nothing to get the money back, and he pursues Antoine and Lisa relentlessly.
