Porsche and Audi begin their brutal dogfight for the lead while Jann Mardenborough's Nissan #23 crew desperately try to get his car out of the garage. Privateers Rebellion amazingly keep up with the frontrunners Audi and Porsche - but when a flaming GT car slams it into the barrier just an hour into the race - it looks like Rebellion's Le Mans could be over almost before its begun.

Darkness blankets one of the world's most treacherous car races - an event that's claimed over a hundred lives - including that of Allan Simonsen, teammate of Aston Martin's Darren Turner. As Turner battles the dark, his mind drifts to his newborn baby. After a brutal crash for Audi's #8 car, it's advantage Porsche. Mark Webber takes the driving seat but there's bad news for Porsche's star driver.

Mark Webber sits in the pits serving his co-driver's penalty. For an F1 champ used to working alone, it's a harsh test of team spirit. Porsche turns their hopes to their #19 car, driven by Le Mans rookies Earl Bamber, Nick Tandy and Nico Hülkenberg. Meanwhile, Rebellion battle with exhaustion and electrical problems, as their driver Nico Prost fights to live up to his father Alain Prost's legacy.

After the back of his car implodes, André Lotterer throws caution to the wind and puts in the quickest laps of the race. Ahead of Lotterer, it's brother against brother as F1 legend Mark Webber and rookie Earl Bamber's Porsches go head-to-head. Way back down the order, Nissan's Jann Mardenborough is just trying to make it to the finish line as his dreams of a Le Mans win go up in flames.
