Life is good in suburbia. Two families celebrate a 40th birthday by flirting, dancing, and laughing carelessly. Their children steal from them, but that's just a small nuisance. Nothing matters when you can afford a bottle of a 70 year old red wine from the South of France. Nothing matters until an uninvited stranger shows up on the threshold of their home. Then, the bottle of "Chateau Rosaline" from 1937 reminds them what is really priceless.
