Please tell me the plot and background of BioShock.

In 1960, the protagonist Jack's plane suddenly crashed next to a strange lighthouse in the vast Atlantic Ocean. Through a spherical diving capsule in the lighthouse, Jack came to an underwater metropolis called Rapture. Rapture was conceived, designed and built by Andrew Ryan, an industrial tycoon born in the Soviet Union.

Rapture relies on the energy released by active volcanoes on the Atlantic Ocean to build a dream utopian city that is completely self-sufficient from water degeneration, electricity to food, air, etc. The residents of Rapture must also be vetted by Andrew Ryan himself one by one, and the so-called "most outstanding representatives of mankind" are selected to integrate into Rapture.

Naturally, wherever there are people, there are classes, and Rapture is no exception. With population and economic development, society is also divided into different classes. It can be known from the recording that a scientist named Bridgette Tenenbaum discovered a unique sea snail in the deep sea that can secrete a strange stem cell. The scientist called it "ADAM."
