Inside Story

First, the story of Richard Giardina and Lisa Keem. He was the life of the party. She was searching for a soul mate. From the very first time Lisa met Richard, she knew he was different.

In this episode you'll meet two extraordinary people who have done just that. And when you discover just how horrific, how pre-mediated, these murders were, it beggars belief that these people could ever forgive.

This is a story about dark secrets, strange rituals and murder.

Go on, admit it. We've all done it. Told the odd porky, gilded the lily, twisted the truth. But the people you'll meet in this episode do it on a whole different level - their entire lives are one big lie. They're are A-grade cheats and con artists and their frauds are so grandiose, so brazen, they will leave you shaking your head in disbelief.
