A rideshare driver is the only witness to one of her passenger's secret affair ... an affair that may be the least of his crimes. When her husband's medical bills become overwhelming, Paula starts a side job as a rideshare driver. One night, she picks up a quiet stranger and drops him off at a Chicago apartment with a beautiful woman waiting for him in the window. When she later recognizes the passenger as a famous musician, and realizes the woman in the window is not his also-famous wife, Paula does what any down-on-her-luck woman would do: She asks for money to keep quiet. But the biggest risk of her life quickly becomes her biggest mistake when a tenant is found murdered in the same apartment building where she left the musician-and she's the only person who knows he was there.
