What does a rheumatologist know about assassinations? Normally, not much. But while watching the news at home one day, Dr. Paul Allen learns that his son, Daniel, has allegedly shot the Democratic presidential candidate. Paul’s specialty is diagnosing illnesses that have otherwise reached a dead end, and with the same vigour he puts into his practice, he begins researching his son’s life to find clues about what may have led to this shocking event. In the process he also tries desperately to reconnect with his son. A psychological thriller (think CSI in Parenthood land) that examines father-son relationships within the modern family.
