Ten people are invited for a weekend on an island by a mysterious stranger, but it turns out he isn't present. At dinner a record is played which accuses each one of the guests of having committed a murder. Shortly thereafter the guests begin to die, one by one until there are only two people left.
Seven guests, a newly hired secretary and two staff are gathered at a manor house on an isolated island by an unknown absentee host and are killed off one-by-one. They work together to determine who the killer is before it's too late.
