Alistair Overeem takes you along for his ride on the rollercoaster to get to his UFC 141 bout against Brock Lesnar.

This latest episode of the video documentary "The Reem" begins at the press conference before segueing into various training sessions. Then we see Overeem fly out to see his mother, who is dealing with complications from cancer.

Finally, right at the end of the video, Overeem touches on the drug test controversy that has been hanging over his head for weeks now. Essentially, it's a blowoff, a way to downplay the issue and turn the focus solely of attention back to the fight itself, which is going to be huge.
