Thomas replied with some good general overview of how to work with the  
client; I'll add some more information specific to what I think you  
are doing. This code assumes you are within the context of a Horde  
application, and that authentication is also valid for IMP. I'm also  
assuming you have the UID of the specific message you want and that  
you plan on displaying some part of it. For this example, I'll assume  
it's one of the main body parts and not an attachment.

// imap object
$imap = $GLOBALS['registry']->mail->imapOb();

// Use the INBOX
$mbox = Horde_Imap_Client_Mailbox::get('INBOX');

// Build a query for the imap server
$query = new Horde_Imap_Client_Fetch_Query();

// Indicate we want the mime structure of the message.
$query->structure();

// If you want flag data...
$query->flags();

// You probably want/need the envelope data
$query->envelope();

// If you want/need the header text, but just peek so we don't set the  
/seen flag.
$query->headerText(array('peek' => true));

// Array of UIDS that you want to fetch.
$uids = array(100, 101);

// Get the results from the server.
$fetch_results = imap->fetch($mbox, $query, array('ids' => new  
Horde_Imap_Client_Ids($uids), 'exists' => true));

// You can access the results like so:
$data = $fetch_results[$uuid];

// Get message headers (returns a Horde_Mime_Headers object)
$data->getHeaderText(0, Horde_Imap_Client_Data_Fetch::HEADER_PARSE);

// This is the base Horde_Mime object, describing the message structure.
$base_part = $data->getStructure();

// This is the mime_id of a plain text body part (if any).
$text_id = $basePart->findBody('plain');
$text_mime_part = $basePart->getPart($text_id);
$text_contents = $data->getBodyPart($text_id);

// Ensure its properly decoded if needed.
if (!$data->getBodyPartDecode($text_id))
     $text_mime_part->setContents($text_contents);
     $text_contents = $text_mime->getContents();
}

That should get you most of the way there. Obviously there is a LOT  
involved in properly fetching and decoding message data.  If you go  
this route, you'll want to be familiar with Horde_Mime and  
Horde_Imap_Client. See https://dev.horde.org/ for autogenerated phpdoc.

You can also look at the code in IMP or Horde_ActiveSync_Imap_Adapter,  
Horde_ActiveSync_Imap_Message, and Horde_ActiveSync_MessageBodyData  
for some more usage...
