Christmas time. Mistletoe and wine. The season of domestics, religion, adultery, drugs, hangovers, alcohol, parties, fights, unwanted gifts, football matches and good fucking will to all men.

And that's just one tour of duty on a TSG van.

Ugly Bus is five cops. Martin. Flub. Dullas. Vince. And good old brain-dead Thrush. Specialist Territorial Support Group officers working a late shift on Boxing Day. Martin Finch is the new sergeant on the group: young, idealistic, following in his late father's footsteps and desperate to make a difference. Unfortunately the old sweat coppers he's now working alongside have other plans...

What begins as a routine shift policing a football match rapidly descends into chaos, and Martin is faced with the question: just how far would you go to fit in? The answer will change the lives of everyone on the Ugly Bus - and the life of a young woman drawn into their orbit - forever.

Always remember: what happens on the van, stays on the van.
