Tiger Cubs (Chinese: ??; literally "flying tigers", alternatively titled Special Duties Unit, is a Hong Kong police procedural television series produced by Lam Chi-wah and TVB. It premiered on Sunday, 24 June 2012 on Jade and HD Jade, and was the first TVB drama to broadcast in the Sunday night time slot since 1995's File of Justice. Tiger Cubs was one of six TVB dramas that were promoted at the 2011 Hong Kong Internal Film and TV Market. Tiger Cubs debuted its trailer at TVB's Programme Presentation 2012 event on 1 November 2011.The drama is renewed for a sequel in early 2013, with a production of 20 regular episodes. Filming for the second series began in June 2013.The drama follows a fictional team of elite paramilitary officers from the Special Duties Unit of the Hong Kong police force. They specialise in counter-terrorism, hostage rescue, and crimes that are deemed too dangerous for regular police to handle. The unit works closely with the Organised Crime and Triad Bureau (OCTB) to crack down on terrorist groups.The highly trained Special Duties Unit (SDU), commanded by Joe Ma, faces a slew of criminals, masterminds and kingpins. Out come the weapons and armour and off they go, always returning with the mission completed. They take down everyone from drug dealers, bombers and kidnappers, a crazy psychiatrist, and the “King of Thieves” Kenneth Ma.This is a masterful creation by TVB; a model for police dramas. This is what TVB is capable of when they put effort and resources into a production. This series features action, action and more action. There’s a lot of explosive scenes, shooting, fighting, the like… When the SDU is not on a mission, they’re doing training exercises. They’re running, climbing and jumping around. You can still admire their physical prowess. There’s always movement on the screen, always excitement in the air that will keep you at the edge of your seat.I really like the format of this series. No plot, just case after case. EaWatch drama online for free.
