A lot of people tell me that they just can't believe it.

They're just like, your own mom did this to you?

Or is it your stepmom?

They'll question me for a second.

Are you really talking about your own mother?

Yeah. I'm Andrea Gunning, and this is Betrayal, a show about the people we trust the most,

and the deceptions that change everything.

Sometimes we hear a story and think,

how could anyone do that to another person,

much less to someone they love?

And worse of all, it often seems to happen to people like Audrey Thompson.

People around me know me to be a little too nice. I'm one of those people-pleaser kind of people.

Audrey grew up in rural Indiana. The big city to me when I was growing up was Kokomo, you know, 25 minutes north.

She spent her entire life in the small town of Tipton, Indiana.

Population, 5,000.

When we asked her how she would describe it,

she said one word, corn.

So if you like that kind of scenery

of just growing up seeing corn and beans, it'd be perfect for you.

Starting at age five, her mom entered her in beauty pageants.

A lot of pageants.

I have like 30 trophies of like first place and second place and then runner up and all that stuff.
