SPOILER ALERT!! - Tom (Max Beesley) and Greg (Paterson Joseph) are enslaved alongside Kevin (Al Weaver) and dozens of others in Mr. Smithson's (Christopher Fulford) coal mine. Meanwhile, the group is desperately hunting for them and follows Billy (Roger Lloyd-Pack), the only lead, to a roadside motel where he is meeting his girlfriend, Sally (Emma Lowndes). When questioned, Billy feigns ignorance and exists under the pretence of asking around while on his trading route, leaving the group with Sally. In the mine, an accident leaves Kevin badly injured. Greg formulates an escape plan by convincing Smithson that he's a geologist and has discovered a gas leak in the mine. However, the group is converging on Smithson's with its own rescue plans, leading to a dangerous game of cat and mouse. Episode ten airs Tuesday, April 13th @ 9:00 p.m. EST/PST on BBC America.
