Plot summary

What is I Know This Much Is True TV series plot?

Here is a short review of "I Know This Much Is True" TV series plot summary.

The show takes place in Three Rivers, Connecticut in the early 1990s. Dominick Birdsey's identical twin, Thomas Birdsey (Mark Ruffalo), suffers from paranoid schizophrenia. With medication, Thomas is able to live his life in relative peace and work at a coffee stand, but occasionally, he has severe episodes of his illness. Thinking he is making a sacrificial protest that will stop the Gulf War, Thomas cuts off his own hand while at a public library. Dominick sees him through the ensuing decision not to attempt to reattach the hand, and makes efforts on his behalf to free him from what he knows to be an inadequate and depressing hospital for the dangerously mentally ill.
