Weekend at Bernie's (1989)

Two friends receive an invitation to a weekend getaway on a luxurious island with their boss. But their idyllic retreat takes a dark turn when the boss is murdered, and strangely, no one but the two friends seems to notice. Fearful of becoming murder suspects, they hatch an unconventional plan - treating the lifeless body as a puppet to convince others that their boss is still very much alive. But little do they know that the killer is determined to finish the job.
