Stoner college student Flic has just received some bad news: she only has one more year to live. 

With her three best friends, Len, Javan and Jenkies, they decide to make it the best year ever - until one night, when they witness a murder. None of them really know what happened, but during a trip to Amsterdam to see their favourite band, Tenacious Toes, the lead singer tells them to use drugs to reconstruct their memories of that night.

Slowly, the events of the hazy night begin to unravel. But what really happened, and is there a connection between them and the victim?
