Young Detective Dee: Rise of the Sea Dragon

The young Dee Renjie (Mark Chao)
arrives in the Imperial Capital,
intent to become an officer of the
law. Empress Wu (Carina Lau), who is
at the start of her reign, has sent
the fiery-haired Detective Yuchi (Feng
Shaofeng) to investigate a sea monster
that stalks the city at night. By
chance, both Dee and Yuchi fight off
the creature when it attacks a
ceremonial procession carrying the
beautiful courtesan Yin (Angelababy)
to be sacrificed at a temple to
appease the Gods. Suspicious of the
stranger, Yuchi has Dee imprisoned.
Dee escapes with the help of visiting
doctor Shatuo (Lin Gengxin) and
together they discover that the upper
reaches of society, including the
Emperor himself, are addicted to a
poisonous tea produced by Yuan’s (Kim
Bum) famous teahouse. Yuan, who was
romantically attached to Yin, has been
missing for months. Dee shadows the
courtesan, who is under Yuchun’s
protection, until the sea monster
reappears. Just as the two men are
about to kill it, Yin reveals that the
monster is her lover, Yuan. Yuan has
been poisoned by a foreign Prince
whose kingdom was overthrown by the
Emperor. As the Prince’s army readies
itself on a nearby island to attack
the capital, a real sea dragon rises
from the deep.
