In an simulated military exercise, squad leader Xiao Ying and all the other soldiers fought along the coastline to prepare for the destruction of the blue landing force. However, Xiao Ying mistakenly touched the button of the explosives and made the exercise a mess. Therefore, he was sent to the base for retraining. The head responsible for the training decided in secret that everything should be started from scratch. Squad finally showed its brightest side on the day of the annual National Army Tactics Contest in the camp and won a medal for the Company Commander competing in five combat skills tests.
