I remember seeing this short film (I think it was a short film) on Dailymotion. The only scene I remember is where the couple is going through their old, empty house that is on the market to be sold. After reminiscing about old times I think the woman finds some champagne or wine or some such thing and if I remember correctly they get drunk and have sex throughout the house, ending up on the landing between the first and second floor, where the realtor, accompanied by a prospective buying couple enter the home and catch them in the act.
That's about all I can remember. If anyone can help me out I'd really appreciate. I can't remember much beyond that, but I'm pretty sure it was a decent little short film or short film series. Thanks!
