Lost at Birth will tell the story of a rather ordinary guy.
Stable job, nice house, comfortable routine, married, with no kids… that he knows of.

In short, his life is pleasantly boring.

To spice things up he has some fun on the side that his wife doesn't need to know about. Then things turn upside-down when a young woman comes into his life…with a birth certificate.
