How well do you know those nearest and dearest to you? Seriously: what do you actually know about them, about the time before they met you? Only the stuff they've told you themselves? Is that good enough for you? It’s certainly good enough for Julia Hardy, a woman in her 40s from New York, who has just moved in with her new boyfriend Eric. But it’s certainly not good enough for her daughter Dannii, who thinks there are things in Eric’s past that he is not telling them. Dark things. So determined is she to find out what they are she convinces her sister and her boyfriend to help her break into Eric’s storage unit where he keeps his possessions. But is it a good idea to try and unwrap someone’s past? Might it not even be dangerous, especially if that past is so neatly and discretely Boxed Up?
