When Shaun decides to take the day off and have some fun, he gets a little more action than he bargained for. A mix up with the Farmer, a caravan and a very steep hill lead them all to the Big City and it's up to Shaun and the flock to return everyone safely to the green grass of home.

When an alien with amazing powers crash-lands near Mossy Bottom Farm, Shaun the Sheep goes on a mission to shepherd the intergalactic visitor home before a sinister organization can capture her.

The residents of Mossy Bottom Farm looking forward to Halloween – until the clumsy Farmer trashes the flock’s beloved pumpkin patch! When Shaun turns mad scientist to fix the problem, things rapidly spiral out of control. With the Farmer missing and a wild beast roaming the woods of Mossingham, all the ingredients are in place for a monstrously fun family adventure.

Shaun bluffs his dimwitted farmer master into bidding for three llamas at a county fair. Once they arrive, however, they cause such chaotic destructive mayhem that Shaun has to carefully remove them – high-speed chases, careful rooftop scrambles and dangerous falls ensue.
