Curious episode this one, a lot of recognisable talent and a decent premise but ultimately not going anywhere.
A group of criminals break their boss Cyril (Kenneth Warren) out of Prison Hospital and sequester him back to a block of flats whilst their plan their next move. The plan was spearheaded by Bender (Tom Bell) and although he thinks the plan is on track, he's alarmed by Cyril's paranoid rantings about Porter (Brian Glover) a rival boss. But is the ranting justified? as we see via flashback that Bender and Porter have had some interactions over the past few weeks.
There's a lot of tense build up here as Bender, nicely played by Bell and his other associate Ronnie - played by Warren Clarke, try to calm their ranting boss down as he gets increasingly paranoid and accusatorial about Bender's reasons for masterminding the escape. All this stuff is nicely performed, if a little tame compared to the language that would be used in a comparable version today. However, though there's enough to the resolution to explain what's actually going on, it's not particularly shocking or memorable conclusion and beyond the performances I'd struggle to find a reason to recommend this to someone else.
