Wonderland is a family drama about how a "white lie" spirals into a full-blown deception that brings two men together in an unlikely friendship. To pay for his daughter Eileen's education abroad, Loke sells his family home and moves into a tiny one bedroom rental. There, he meets Tan, his neighbour who helps him write his letters to Eileen, and read her letters to him. Meanwhile, Tan finds comfort in Loke's dedication to his daughter, as he yearns for a reconciliation with his estranged daughter. Tragedy strikes as Eileen is killed in an accident whilst studying in the US. Tan happens to be the one who takes the call and receives the bad news. In an attempt to spare his newfound friend the immense grief, Tan, in a spur of a moment, decides to withhold the truth from Loke and is hoping to find the right time to break the tragic news. The lie spirals out of control as Tan pulls in other residents to help him perpetrate the lie - faking letters, photographs and even voice/cassette recordings. One day, Loke passes out and the doctor diagnoses that he has stage 4 cancer and has only weeks left to live. This stuns Tan and puts him in an impossible situation as he agonises over whether truth or mercy should prevail.
