You can catch a free screening of the Bushwick stoner-slasher flick “Psychotic!” this Friday at Cobra Club to celebrate the cannabis-lover’s holiday of 4/20.  

The crowdfunded thriller, shot and produced primarily in Bushwick, follows a group of “hard-partying hipsters” as they are stalked and savagely murdered by the Bushwick Party Killer —  a masked maniac with a unquenchable thirst for bohemian blood.
