It starts with an "amnesia" joke: Annie's husband Cain tells her that his best friend Elias is her husband, then openly flirts with her best friend Raven in the front seat. Stunned, Annie plays along in the back of the SUV, and with every bump in the road she is pulled closer to Elias, who is not as unaffected as he pretends.
