After discovering their significant others are siblings, two resentful exes must spend Christmas under one roof — while hiding their romantic history.

American car designer Carroll Shelby and the British-born driver Ken Miles work together to battle corporate interference, the laws of physics, and their own personal demons to build a revolutionary race car for Ford Motor Company and take on the dominating race cars of Enzo Ferrari at the 24 Hours of Le Mans in France in 1966.

Based on the Pretty Little Liars series of young adult novels by Sara Shepard, the series follows the lives of four girls — Spencer, Hanna, Aria, and Emily — whose clique falls apart after the disappearance of their queen bee, Alison. One year later, they begin receiving messages from someone using the name "A" who threatens to expose their secrets — including long-hidden ones they thought only Alison knew.
