Myra is een paranormaal begaafd medium in Londen. Ze draagt haar zwakke echtgenoot op een meisje te ontvoeren, om de rijke ouders te chanteren. Dan biedt ze diezelfde ouders aan een séance te houden, en vervolgens komen haar ware motieven voor de ontvoering naar boven...
Nee, helaas is Seance on a Wet Afternoon nog niet beschikbaar op Netflix in Nederland.
