After spending many long hours perfecting a new card trick, comic magician David Williamson — whose motto is "take risks and be prepared to fail" — attempts to perform it on live television, only to have it ruined by a smart alec kid named Murray.

Twenty years later, at the 2011 International Magic Convention in London, Williamson was reunited with Murray, and finally got a chance to complete the trick (reunion occurs around the five-minute mark).
