Spanish horror sequel. The film follows on from the end of the second instalment, '[Rec] 2' (2009), with a swat team sent in to the building to recover the now possessed Angela (Manuela Velasco). They take her to a ship offshore that has been specially equipped to deal with the outbreak, but as her blood tests come back negative, those on board have no idea that Angela recently possessed the demonic virus. The crew think they have the situation under control, but after analysing Angela's tapes, they find themselves trapped on the boat with another outbreak imminent, their communications severed and a storm heading their way.
