When the TARDIS is invaded by two Sontaran warriors, the Doctor is forced to seek aid from elsewhere. His former companion, Tegan, is brought on board, together with a young boy named Gareth Jenkins. With Gareth's help, the two Sontarans are defeated - but then a far more hideous image suddenly appears on the TARDIS scanner, speaking in a bizarre alien language...
