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.
Unfortunately the movie Chatroom is not yet available on HBO Max.
