On Sarah's birthday, her best friend Victoria gives her a genetic testing kit as a gift so she can learn more about her family's lineage. But that night, Victoria is tragically killed. Weeks later, Sarah gets a knock on her door, and it's the police. As their homicide case ran cold, they decided to run the killer's DNA through the genetic testing site's database and there was a match: Sarah.

Sarah, who's grown up as an orphan, has lived all her life in the small town where she runs an ice cream parlor with her brother Will and Cousin April. When her best friend Victoria gifts her a genetic testing kit, she's excited to learn more about her family. But then, Victoria is murdered. Traces of DNA found on her body are a close match to Sarah's from the testing site's database. The killer must be related. Is it her cousin Lyle, who's been acting strange lately? Then, when April follows up on a clue, she too is killed. Now, all evidence points to Will, who had been having an illicit affair with Viktoria. Sarah can't believe it. Is it a set up? As she gets closer to the truth, Sarah soon finds herself in mortal danger.
