In the beginning, it was heady, fun.

MEGHAN VERIKAS: he is very charming.

She was swept away. 

MEGHAN VERIKAS: I don’t think I’ve ever had somebody tell me I’m beautiful that much.

But without warning, it all turned from love story to crime story.

MAGGIE WHITLEY: He’s a relentless tsunami.

SAMANTHA KNECHT: He doesn’t care who he affects.

ANDREA CANNING: This is, like, out of a movie?

MEGHAN VERIKAS: It is. It is.

A thriller.

AERIAL WASHINGTON: I ran across the street yelling, “Leave her alone.”

With secret recordings.

A fake death, and another death, that was all too real.
