Directed by Alexander Payne, The Holdovers follows a small group of people stuck on the campus of a boarding school over Christmas of 1970. This group consists mainly of Angus (Dominic Sessa), a student with abandonment issues, Professor Paul Hunham (Paul Giamatti), a curmudgeonly teacher who takes his job extremely seriously, and Mary Lamb, played by Da'Vine Joy Randolph (Only Murders in the Building), the school's chef whose son was killed overseas in Vietnam.
