Constance Day (Evelyn Stewart) is a secondary villainess in the 1966 Italian action film “Special Mission Lady Chaplin”. The original title was “Missione Speciale Lady Chaplin”. This is the third and final of the Ken Clark 077 Eurospy flicks.
Constance Day was a partner in crime and business to Lady Arabella Chaplin (Daniela Bianchi), who was a fashion stylist and owner of an atelier in Paris. Lady Chaplin ran a criminal assassin business on the side. They work for the multi-millionaire Kobre Zoltan (Jacques Bergerac), where Chaplin serves as his mistress.
The film begins in Spain, with Lady Chaplin showing up to an abbey dressed as a nun driving a Citreon delivery van. She carries in a basket full of fresh linens that hides a machine gun tucked inside and shoots two false monks before they know what is happening. She then turns her gun on the radio transmitter. After leaving, she is met near the sea by her partner Constance. Chaplin gets out of her nun outfit revealing a yellow bikini and the two push the delivery truck over the cliff into the ocean. They calmly walk to their hotel and lounge out at the pool.
Their goal is to resurface the sunken American atomic submarine USS Thresher, which sunk twelve months previously. On board are sixteen Polaris nuclear missiles.
Constance next appears when she helps Lady Chaplin out of her old lady disguise. Later that night, CIA agent Dick Molloy (Ken Clark) spies on Chaplin and Constance as they attend a dinner party. Zoltan is there betting on his pet scorpions fighting.
Chaplin arrives in London where she is posing as a military officer. Zoltan and Constance are monitoring a meeting between Chaplin and another buyer. It appears as if Constance and Zoltan are more than just friends, which seems as if she is doing this behind Chaplin’s back.
Next, we see Chaplin wearing a red wig and making contact with a prospective buyer, Hilde (Helga Line) at another fashion show. Jacqueline goes undercover as one of Lady Chaplin’s models. Constance is suspicious of the new model. After Constance models one of the red dresses that Chaplin has designed with the new missile propellant fuel inside it, the dress is purchased by Hilde. Chaplin and Hilde work out the details in the backroom and they agree with the sale. Hilde presents a case full of diamonds worth 5 million dollars.
While snooping in the backroom, she is discovered by henchwoman Constance who points a gun at her. Constance makes the comment that “I knew there was something suspicious about you”. Jacqueline is able to kick the pistol out of her hand and shoot Constance with her own gun, leaving the beauty behind in a pool of fashion. Unfortunately for Jacqueline, she suffers the film’s most outrageous death, when she is blown up by an exploding dress.
Zoltan called to let Chaplin know that Constance was killed. He invited her to meet him to get the missiles.
