The trial has finally commenced as the Episode 4 of "People vs. O.J. Simpson" arrived on small screens. However, the defense is slowly heading to the rock bottom as Robert Shapiro started to lose the rope into the case.

According to Rolling Stone, the loopholes in the defense are starting to appear. Shapiro asked his co-lawyers if their client really did but to no avail. However, they were able to overturn the prosecution by "blocking every turn."

What will happen in Episode 5? Dubbed as "The Race Card," IB Times was able to gather the official video synopsis for the next episode.

"Johnnie Cochran (Courtney B. Vance), the Dream Team's new, lead attorney, will be taken back when he learns his protégé is on the prosecution," as we quote. However, he is trying not to be affected by his friendship with Chris despite the fact that they are now on opposite sides

But he will not be the only hindrance that Chris has to surpass for convincing everyone that O.J. is not guilty. He became doubtful of the prosecution's witness, Mark Fuhrman, so he conducted as discreet background check on him.

The FX drama features Sterling K. Brown as Christopher Darden, Kenneth Choi as Judge Lance Ito, Christian Clemenson as Bill Hodgman, Cuba Gooding Jr. as O.J. Simpson, Bruce Greenwood as Gil Garcetti and many more.

"The People v. O.J. Simpson" airs on Tuesdays 10 p.m. EST on FX.
