A videotaped clue from Trudy provides Monk with the clues he needs to solve her murder - but he has very little time to catch her killer while finding out what poisoned him.
An investigation draws Monk back to the place where he first heard about Trudy's murder - but his fate has been unfortunately sealed as he retraces his steps on that fateful day.
Monk's agoraphobic brother Ambrose asks for his help, convinced his neighbor has been killed by her husband. But all the husband seems focused on is winning the pies at the local fair.
