Throughout their friendship Ken Andrews was the unchallenged party leader of his posse and the chief instigator of elaborate, infamous, hilarious (and slightly damaging) hazing rituals at all his buddies' stags and parties.

Today is Ken's stag. The door just opened for payback from all those he has victimised over the years. Ken becomes increasingly paranoid about the fate that awaits him, while at the same time a little psyched to see the "respect" his friends will show him through the elaborate planning and execution of his haze.

But there are two problems with Ken's expectations:
1. He was always the leader/planner so now the group has no chief, and...
2. He waited a long time to get married so now all of his pals are going through early mid-life crisis' and find the concept of hazing rather juvenile, mean and slightly exhausting.

Stag follows five best friends on an eventful day filled with revelations, white lies, a very weird bar fight, new loves, a groped celebrity, a stripper with ulterior motives and a tropical fruit where the sun don't shine.

All resulting in the worst stag ever held.
