Uke attacks 5th Form (Shomen-uchi).
Nage irimi's (enters) into the attack, using 'basic' defence and continues to push through into Uke rotating his arm a full 360 degrees. Nage then controls with a lock to the shoulder and reduces the gap to the minimum. This enables Nage to continue to pin Uke into the floor.

Nage = Sensei Derek Eastman.
Uke = Sensei Mark Eastman.
