Eyeball

“A blinding vision of horror.”

Paulette Stone (Martine Brochard) is an American tourist on a guided bus trip through Spain, sharing seats and dinner tables with a group of strangers. Umberto Lenzi sends them through Barcelona as two of their number turn up murdered, each missing an eyeball. Paulette begins to suspect the man she has grown close to, Mark Burton (John Richardson), and the police inspector tells them the killer is still on the tour.
