Death Ship (1980) (UK-import)
Unknown to the vacationing passengers partying the night away aboard a luxury ocean liner, their holiday is about to come to a very abrupt and watery end. Following a collision, the few surviving passengers board a seemingly derelict vessel but, once aboard, they soon realize they may be facing an even worse fate than their late fellow passengers as a malevolent presence onboard is intent on destroying its newly arrived guests in the most gruesome and terrifying ways imaginable.
