Chip and Skip love the big old house they have just moved into with their parents, and seem set for adventure when they find a mysterious treasure chest in the attic. Hidden in the corner of the chest is a bag, which contains two pairs of glasses with tiny dials. When they put them on and turn those dials they are catapulted back in time to 1912, and find themselves trapped aboard the doomed Titanic with a quest to fulfil. But time is running out! Will they be able to solve the mystery - and make it home - before the ship sinks?
