Inside No. 9: Tom and Gerri

SINOPSE

Primary school teacher Tom tries to repay a good turn from a late-night caller, but he gradually becomes the victim of his own generosity. As time passes, his new friend Migg becomes an increasingly dominant part of Tom's life, threatening his relationship with aspiring actress girlfriend Gerri. Steve Pemberton and Reece Shearsmith star, with Gemma Arterton (Quantum of Solace) and Conleth Hill (Game of Thrones).
