When Denis Midgley's father is rushed to hospital, Midgley drops everything to be by his side. They've never really got on, so Midgley wants to be sure he's there if his father ever regains consciousness. As he hates his job as a schoolteacher, and his home-life with his wife, her senile mother and their insolent teenage son, he has no qualms about lingering around the hospital. But as days turn into weeks, his father obstinately refuses to 'slip away', and Denis' motivation for staying by his father's bedside has more and more to do with Valery, a young nurse.
