Deborah, in her forties, is as mad as a dog chasing its tail to lose its head. She downloads a dating app and bumps into Mr. R., a guy who looks like he came out of her wettest dreams. He invites her to dinner and Deborah, all excited, goes.
But before she gets there she gives in to temptation and gives herself to an irresistible stranger. But, holy hell, the moral hangover hits hard and she runs away like a runaway cat.

But destiny is a son of a bitch and decides to play a trick on this story: that stranger is her new boss. Now, Deborah will have to struggle to deal with the sexual tension in the office while trying to hide the fire that burns inside her every time she looks into that scoundrel's eyes.
