AMUCK!

Greta, a beautiful blonde American, is hired as the new secretary to Richard Stuart, a famous novelist who lives on an island near Venice with his wife Eleanora. Sally, the previous secretary, had disappeared without a trace. Unbeknownst to Richard and Eleanora, Greta has taken the job in order to investigate the disappearance of her lover, Sally.

Greta learns that Sally was accidentally killed in the heat of passion during one of the kinky sex games the Stuarts hold in their mansion occasionally; a hulking man-brute named Rocco lost control and strangled the girl. The bizarre couple then kills their butler when he attempts to blackmail them over the incident. All that remains is for Greta to be disposed of, then the crimes will never be uncovered. Eleanora lures Greta into a three-way private orgy with Rocco and herself, in an attempt to get the easily excited Rocco to repeat his careless crime of passion one last time.

Eleanora attempts to dispose of Greta by luring her into a private orgy with Rocco, hoping he will kill Greta in a fit of passion as he did with Sally.

The climax underscores the lethal intersection of sexual obsession and self-preservation among the film’s characters. Eleanora’s plot to use Rocco’s violent impulses as a murder weapon echoes the film’s recurring motif of desire spiraling into violence. Greta’s entrapment in this dangerous game exposes the extent to which the Stuarts will go to preserve their secrets, reinforcing the film’s atmosphere of paranoia and erotic menace.
