Daniel and Amber's wedding may have some notable relatives missing - not least Scott and Charlene! - but Tom Ramsay does manage to make it to Erinsborough for the big day.
Tom also has some vital information to share, as he arrives back just after Daniel, Amber and Imogen have become intrigued by a Robinson family mystery. Daniel's great grandma Agnes Robinson once lost a pearl ring in mysterious circumstances, but it seems that Tom may know what happened to the missing heirloom when he reveals that it is down an abandoned well in the area.
Unfortunately, this revelation soon leads to disaster when Daniel goes in search of the ring on his wedding day with help from Imogen and they both get trapped down the well, leaving an oblivious Amber standing at the altar...
