Prat was a renowned actress who had her heyday in Argentine cinema and theatre during the 1960s and 1970s. She began her career after being chosen by little-known actresses who could adapt to the film budget of that time.
In the film, she was the “fetish” actress, along with Susana Beltrán, of the director Emilio Vieyra with whom she worked in seven of his films, allowing her to act with stars such as Norberto Aroldi, Osvaldo Pacheco, Ricardo Bauleo, Soledad Silveyra, Federico Luppi and Sandro, among others.
In 1965 she was arrested along with Emilio Vieyra for filming nude scenes for the film Feast of Flesh (Placer sangriento).
On television, she was part of the staff of the humorous program La Nut in 1965 and later in La butaca del batuque in 1970.
