Meet Martin, JJ, Jess, and Maureen. Four people who come together on New Year's Eve: a former TV talk show host, a musician, a teenage girl, and a mother. Three are British, one is American. They encounter one another on the roof of Topper's House, a London destination famous as the last stop for those ready to end their lives. This is a tale of connections made and missed, punishing regrets, and the grace of second chances.
