"The Hexpert" is the 20th episode of Thunderbirds Are Go!. It was broadcast on 12th December, 2015.
Professor Alice Lungren accidentally locks herself inside a vault which is being used to store unstable matter. There is only one person who has successfully broken into a vault like this - Parker. Colonel Casey of the GDF recruits Parker for the job, but the safe cracker ends up locking himself and Lady Penelope inside as well. Virgil and Scott transport the vault to an isolated area on Thunderbird 2, where Parker and Penelope must try and free themselves and the scientist before the anti-matter explodes.

- The Hexpert is a modernisation of the classic Thunderbirds episode Vault Of Death.
- The password that must be entered to unlock the vault (3-0-0-9-1-9-6-5) is a reference to the original broadcast date of Trapped in the Sky, the first episode of the original series (30/09/1965).
- In the original draft of the script, two scientists, implied to be a couple, were trapped in the vault. One would have pushed the other out the door, becoming locked in the vault in the process. This script was cut, however, for a script involving Lady Penelope and Parker.
