Unfortunately, you won't be able to retrieve it. "All video history is deleted on a rolling basis. This means that, depending on the Nest Aware subscription you have, older saved video is deleted from the cloud after a certain number of days." In your case, without a subscription, that would be 3 hours.

It's probably not legal or ethical for Google Nest to store video history from our cameras without our giving permission, either by buying a camera with a free 3-hour video history window or by buying a Nest Aware subscription.
