When strangers Jim, Eva, Emily and Mo meet William online in his new 'Chelsea Teens!' chatroom, they're completely seduced by his fast-talking, charismatic character. But beneath the surface lies a much darker truth. William is a dangerous loner, channeling all his energies into cyberspace. He's become an analyser, a calculating manipulator who finds it almost impossible to interact normally with others in the real world, instead turning his hand to manipulating people online.
