The US Army asks the Howe brothers to modify their most famous vehicles, two high-speed tanks called Ripsaw MS1 and Ripsaw MS2. Ripsaw MS1 is a remote controlled tank and Ripsaw MS2 is a manned version. Now, Mike and Geoff must make Ripsaw MS2 operate remotely as well. In the middle of it all, Mike, Geoff and their amazing Ripsaws must star in a TV show called "Popular Science: The Future Of..." The publicity is great, but the rigorous test-drive for the TV cameras ruins the wheels on MS-2 and the twins have to order new ones. Will the new wheels arrive on time? And will a last minute technical glitch jeopardize H&H's all important military contracts?

美國陸軍要求郝氏兄弟協助改良陸軍最知名的載具：高速戰車 “粗齒鋸 MS1” 與 “粗齒鋸MS2”。粗齒鋸MS1 是無人遙控戰車，而粗齒鋸MS2則是載人戰車；這次的挑戰是把粗齒鋸MS2也改成遙控。除此之外，邁克和傑夫還得帶著粗齒鋸戰車登上電視節目”科技新時代”（Popular Science: The Future Of）。擁有媒體宣傳固然好，但是他們為電視攝影團隊進行的試駕卻造成MS-2的車輪毀損， 害得兄弟倆必須緊急訂購新車輪，但新車輪能否準時送達？這個最後一刻出現的技術問題是否會危及兩兄弟與軍方的重要合約？
