Catch red handed. Everyday slang for catching someone doing something secret, forbidden, or embarrassing.
Короче пока будущая мама была в больнице — муж с этой «некрасивой» переспал. Их застукала несостоявшаяся тёща. Был скандал.
In short while the expecting mum was in hospital her husband slept with this “ugly” one. They got caught by the not yet mother-in-law. It was a scandal.
