Evil Weed is a 2009 horror film written and directed by David Wexler.

It was filmed for an extremely low budget of $30,000 over five days in Montauk, New York, as a tip of the hat to the old B-Movies of the sixties and seventies.

[1] Emily and her sister Danielle play host to friends at their parents' country house in the Hamptons.

Murph, Emily's boyfriend, has chosen this occasion to propose, their respective best friends seem to be hitting it off, and Danielle's alienated boyfriend scores in the clutch by supplying the drugs.

But when his bag of unicorn weed livens up the party, some of the group begin to suffer from a weird reaction.
