White Collar S01E05 The Portrait
When a painting is stolen, Peter and Neal are tasked with finding it. They get a lead on the thief, they set a meeting but something goes wrong and the man disappears. They try to find him using info he uttered at the meeting. Later a curator from a museum in Europe claims that the painting was stolen from the museum years ago and when the painting is recovered, he expects it to be returned to him. Neal talks to the owner and learns that her family has a connection to the painting, which makes Neal wonder who the painting really belongs to.
