Cosmo keeps the books for the mobster Max and lives by himself beneath a retirement home, with no girlfriend and no dates, though he sees Honey, a prostitute, regularly. When Gordon takes over as boss, he promotes Cosmo to hitman. Steve, the mob's current hitman, shows him the ropes and notices that Cosmo is calm under pressure and an excellent shot. His first job, on a delinquent debtor, leaves him tense and remorseful, and Honey suggests yoga.
