Alexandra (Stephanie Niznik) and Jason (Greg Cromer) are a married couple whose yacht fails to withstand a storm at sea. They're saved from the stormy waters by Capt. Bigelow (Daniel Quinn) and his crew, who man a cargo ship. Jason is heavily drugged by the ship's doctor, Gerbac (Richard Moll), and realizes something is amiss when he comes across corpses. Meanwhile, Gerbac is working on a dangerous scientific experiment using spider eggs, which he hopes to implant in Jason's body.
