A Dead Canary (2019)

Set in the Welsh valleys, during the 1950s, we follow the story of Gwyn, a fairy-tale crazed boy whose Father works tirelessly at the coal mines with his canary. However, due to his Father's tales, Gwyn believes his Father spends every day venturing down the rabbit hole through Wonderland. So, when his Father is tragically killed in a gas explosion, Gwyn thinks his Father must be lost down in Wonderland. Despite his Mother's tears, Gwyn doesn't understand all the fuss and starts to grow frustrated that no one is looking for his Father down the "rabbit hole." It is only at the funeral, where after hearing enough nonsense, Gwyn decides to rescue his Father himself. With his sword unsheathed and shield at the ready, he marches down the mountain, unaware of the horror that really lies beyond the rabbit hole.
