Account, report, chronicle, version, story denote a statement of actual events or conditions or of purported occurrences or conditions.
An account is an oral or written, detailed, often firsthand statement.
A report is an account, usually of something witnessed or investigated, given to an employer or a superior.
A chronicle is a detailed and extended account or report of events in their order of occurrence.
A version or story is a statement of purported facts. Version always and story often imply contrast with another statement of the same events and, usually, difference in details. But whereas version commonly implies difference of detail or of interpretation owing to limitations in each point of view, story often implies actual or suspected falsification.
