Pentimento (1989)

In this frothy comedy, Lucie never knew her father, but she somehow finds out he has recently died and is to be buried on a certain day at a certain cemetary. In a belated attempt to connect with her roots, she rushes to the cemetary and joins a funeral gathering. She gets to know the people at the ceremony and is soon embroiled in an art smuggling scheme and has some (probably incestuous) romantic feelings for a young man she believes may be her brother. Eventually she finds out that she went to the wrong part of the cemetary and that these people are not her kin.
