Tis politsmanas to... kangelo (1981)

After patenting a groundbreaking invention, Rena Fraggeti, a happily-married housewife to the esteemed scientist, Marios Fraggetis, senses that there's definitely something wrong going on with his behaviour. Soon, things will go from bad to worse, when a dazzling industrial spy is assigned the relatively easy task of seducing the middle-aged family-man, intent on getting her hands first on the lucrative innovation. But, as Rena travels all the way to the picturesque island of Corfu to see first-hand her beloved in action, slipping into her cousin's police uniform will be the first good idea in a long time. Now, all those wrongdoers who get in Rena's way shall get what they deserve; however, can a law-enforcement uniform save her marriage?
