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.

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.
