A filmmaker has to deal with obnoxious producers, uncooperative weather, and a troublesome cast -- not all of whom have opposable thumbs -- in this satiric comedy-drama. Rosta is a director whose latest project is an ambitious film that draws parallels between the lives of humans and animals, and as illustration he's cast the members of a local nudist colony, who are to interact naked with a group of apes. However, the cold weather doesn't do much for the esprit de corps of his human cast, while the primates predictably refuse to take direction. Meanwhile, Rosta's backers are demanding more comic relief, the screenwriter argues for a more emotional approach, and Rosta's family shows up unannounced, getting in the way despite their best intentions and also has complications in the relationship with his lover.
