Wanneer filmmaker Dean zijn intrek neemt in een Airbnb, komt hij er tot zijn verrassing achter dat hij niet de enige bewoner is. Hij maakt er kennis met het zeeschelpje Marcel, zijn oma Connie en het huisdier Alan. Ooit maakten Marcel en Connie deel uit van een groep schelpen, maar die zijn ze uit het oog verloren. Dean bekommert zich om hun lot en besluit een documentaire over het tweetal te maken.
Nee, helaas is Marcel: The Shell with Shoes On nog niet beschikbaar op Netflix in Nederland.
