A young couple have a romantic weekend away, but find it derailed a little by a birth control mishap. What follows is a weekend of dealing with that, while also joking around with what might have been. The result is a nicely played short where the actors have a nice mix of jokey remoteness, but with just enough reality in there to give it a slight edge. The natural way between them helps this, and neither Silver or Siegel feel like they are really acting more than they are chatting. The animation has a roughness to it that may jar with those for whom Wallace & Gromit are their only exposure to stopmotion; but the rough edges do fit with the approach and the material. Within that though it has many nice designs and features (the emptiness of some shots for example) which work well. I would have liked a bit less nudity, as I found it distracting - were it life action it would not have been the case, so it felt a bit like the film was making a point because it could.
Overall, it doesn't have great built or tension, but it is nicely natural throughout, and engages via that.
