Synopsis:
Rex the Wonder Dog witnesses three men murder a professor outside his house. Phillip, the brother of Rex's owner Danny, is passing by when the murder happens. The killers knock out Phillip and frame him for the crime. Rex tries to stop them, but he fails. The dog does remember the smell of a distinctive flower worn by one of the crooks. Rex follows the smell and locates the crooks. He relentlessly runs them down, forcing one of them to confess which clears Phillip of the murder.
