When a robber enters the bank and says, "Hands Up," to the cashier, the latter obeys, but at the same time he presses a pedal with his foot releasing a trap door and dropping the crook through the floor into the police station below. Here he finds himself before the sergeant's desk. His trial is brief for the sergeant gives him a crack on the head, and also presses a pedal dropping the criminal into a cell below. The River Gang swear revenge upon the bank and lay a deep plot. In the meantime the son of the president finds a map indicating a buried treasure. He starts digging and tunnels under the bank and into the vault where he discovers gold. Father and son not only discover that they have dug into their own vault, but also find the vault filled with members of the River Gang.
