Reunited by their parents' death, two brothers, Alister and Oscar, meet at a storage unit to sort through a lifetime of belongings. What begins as a quiet, somber task quickly unravels as the confined space and charged memories force years of unspoken tension to the surface.

The brothers' strained interaction gives way to a raw, emotional confrontation, unearthing a deep-seated conflict from "that night" which precipitated one brother's move to New York. As they grapple with differing recollections of their parents and their past, they must navigate a minefield of grief, guilt, and perceived abandonment. "Storage" is an intimate drama that explores the painful, complex nature of sibling bonds and the difficult, necessary journey toward understanding and reconciliation.
