Take the drawing style of Ed Gorey, the sensibility of doom of Abner Dean, and the Sysyiphean zeitgeist of, oh, a filmmaker working in Communist-era Eastern Europe, and you'll have an approximate idea of the feel of Ice Merchants.
I'd warn you that any description of the plot would be full of spoilers, but the IMDB tagline itself is full of spoilers! My advice is to watch this cold, without any particular description of the plot, for best effect. You'll get a very deftly done, real sense of jeopardy for the characters, as well as experiencing the strangeness of the whole premise as one is meant to.
It's a parable for loss and recovery, grief and holding on to love, but wordless and without engaging in sentimentality. There's a reasonably nice revelation with a laugh out loud moment as we see something decidedly inexplicable and seemingly extraneous come in at the end. It's really quite touching, and again, if I explained the plot even a little bit, you'd likely lose the emotional sense that this film very adeptly creates.
This was not my first choice among the Oscar nominees for best short animation (we saw them all at one sitting) but it's a credible runner-up. If you're not literally on the edge of your seat watching this, I'd be surprised.
