“In Extreme Sisters, we will introduce sets of inseparable sisters whose bonds are raw, honest and perhaps a little unconventional. Their sibling kinship brings the meaning of sisterhood to a whole other level," Lee said of the series. While these sisters are confident in their closer-than-ever bonds, the show will take a look at what happens when the opinions of society, their family, friends and partners come into play and if their sisterly connection is strong enough to withstand the pressure.
