Jennifer Shannon can always find a diamond in the rough, when it comes to garage sales, that is. Whether it's a new antique to sell at her consignment shop, an Atari game for her son or a piece of furniture for her handy husband Jason to refurbish, she has made a career out of her treasure hunting prowess. When a string of burglaries hits her town, Jennifer's keen eye for detail and her natural problem solving instincts even help her see the connection between these burglaries and local garage sales! Jennifer works with Detective Adam Iverson to investigate her theory that the perpetrators of the burglaries are fellow garage sale regulars. The case escalates to dangerous levels when Jennifer discovers the dead body of her friend. Even though the deceased's husband, Ben Douglas, finds nothing missing in their house, and the police label the death as accidental, Jennifer suspects that the death may be related to the burglaries.

Jennifer Shannon (Lori Loughlin) has a gift for finding rare treasures hidden in garage sales that she can resell at her consignment store, Rags to Riches. But her keen eye for finding valuables also gets her involved in the criminal investigations that happen at the very second-hand sales she frequents. When Jennifer's friend and self-storage facility owner Martin (Michael Kopsa) turns up murdered-just hours after auctioning off an abandoned storage unit full of unique items to Jennifer-she is immediately pulled on the case as a key eyewitness. Working with Detective Lynwood (Kevin O'Grady), Jennifer helps single out a disgruntled customer as the prime suspect, while she and her business partner, Danielle (Strange), sift through boxes from the auction. As her husband Jason (Bacic) worries about her safety, Jennifer starts to get over her head when there is a break-in at her store, and a run-in with Martin's angry wife. Then, Jennifer and Danielle discover their new merchandise contains the sparkly evidence they needed all along to nail the surprising real culprit, and they must race to save a life-and put their own on the line.
