UK pubcaster Channel 4 has ordered a 10-part series starring polygraph examiner Dan Ribacoff.

Produced by UK indie True North, The Naked Truth (10 x 45 minutes, working title) will see couples, exes, friends and family members sit down for intimate and brutally honest conversations they thought they would never have as Ribacoff administers a lie detector test.

The participants intend to raise issues that have bothered them for a long time and hope that the series will bring about a resolution.

“The strength of the format lies in its stripped-down simplicity, which has created a series that is really compelling,” said True North executive producer Fiona O’Sullivan in a statement.

“We all have a burning question about a relationship, especially ones that have broken down, and watching people tell the truth is proving both fascinating and heart-warming,” added Channel 4 head of features Greg Wilson, who commissioned the show.

O’Sullivan is exec producing with Stuart Froude serving as series director.

An air date has not yet been announced.
