A collapsible escape ladder within a storage container. The container has an upper lid connected to the lower rung of the ladder. The container's lower section is connected to the ladder's upper rung section and a dwelling's structural component. During an emergency the lid is thrown from a window pulling the rest of the ladder to its full unfurled length. The lower ladder rung is attached to the lid which by its weight stabilizes the ladder while its upper rung is firmly fixed to the container's lower section and dwelling.
