Switch - Season 2 Episode 21 The Hemline Heist

A fashion designer is murdered three times simultaneously as he presents during a fashion show -- by drinking cyanide-laced champagne, getting shot and having a spotlight tumble onto his head. The rest of the episode is shown in flashbacks, as the story unfolds of how people stole the formula for his latest show-stopping fashion and tried -- independently of each other but at the exact same moment -- to kill him for trying to find out who did it. (The three killers are all caught trying to escape in a coda at the end.)
