Two of the Minister of State's staffers are found murdered and suspecting a fascist coup, the Minister figures he will be next. Senorita Rio gets on the case and follows her leading suspect to his home where she finds him also recently dead. As she is trying to make sense of it, the real murderer shows up and wrestles her down, and ties her up, leaving her alive because she is "too beautiful to die". He exits with intentions of assasinating the president. With a little outside help from a small boy, Rio is freed and pursues the killer; there is a shoot out, and the fascist dies and the forces of freedom and peace prevail once again. In the pics below we see her manhandled by the murderer, tied up and eventually freed. Senorita Rio was one of the big guns in Fiction House's arsenal of good girls, which also included Sheena and Tiger Girl.
