On a Sunday morning in 2010, Nick and Heidi Firkus should have been getting ready to go to church. Instead, police received a series of distressed 911 calls ― first from Heidi, then from Nick ― claiming that someone was breaking into their home. When they arrived on the scene, they discovered that Heidi had been shot dead, and Nick had a gunshot wound to the leg. As authorities began investigating, they discovered that not only was the couple in massive financial trouble but were set to be evicted from their home the very next day. With no immediate leads, the case went cold, and Nick moved on to marry and have children with a woman named Rachel. Years pass with no updates to the case, and it seems like life has gone back to normal for Nick … until Rachel finds something in Nick’s sock drawer that changes everything she thought she knew about her husband.
