The new series of Red Dwarf is to return to Dave in September.

Red Dwarf XI will air from September 22 at 9pm, but it will also be available online a week early from September 15 on the UKTV Play website.

Red Dwarf XII has already been filmed and will air in 2017.

The cast will still feature Lister (Craig Charles), Kryten (Robert Llewellyn), Rimmer (Chris Barrie) and Cat (Danny John-Jules).

A synopisis of the six-part series has already been released as follows:

4. OFFICER RIMMER

After a scandalous piece of good fortune Rimmer saves the life of a bio-printed Captain and is promoted, fulfilling his life-long dream of becoming an Officer. He immediately opens an Officer's club, which is out of bounds to the lower orders, and uses the bio-printer to fill it with versions of himself.

5. KRYSIS
