Detective Conan: Quarter of Silence (2011)

The governor of Tokyo gets a threat letter and the subway he later travels on explodes and kills him.
As Conan investigates, he realizes that this present day mystery ties in with a mystery that occurred eight years ago in a mountain town.
A young boy by the name of Touma Tachihara fell into an abyss and lost consciousness. He had only just awoken, but remembers nothing of his past.
Conan soon realizes that the key to solving this mystery lies within the boy's forgotten past, and tries desperately to revive Touma's memories.
But an even darker threat looms ahead as a large dam located near the mountain town is rigged with time bombs and there are only fifteen minutes before all the bombs blow and the town is crushed in a torrent of water.
In a desperate race against time, Conan must perform one of his most daring rescue missions and cheat death in this heart-pounding survival mystery.
Can he beat the clock, or will things melt under the storm? Find out as the clock is ticking on the Quarter of Silence!
