"I Can Only Imagine 2," a faith-based drama now in theaters, continues the true story of MercyMe frontman Bart Millard, exploring his life on and off stage following the success of his hit song and the first biopic. The sequel focuses on the challenges Millard faced when his young son, Sam, was diagnosed with Type 1 diabetes, leading to hypervigilance and tension as Bart tried to protect Sam while Sam pursued his own musical ambitions. The film also delves into Bart's friendship with fellow singer Tim Timmons, who battled incurable cancer, and how their shared struggles inspired MercyMe's 2017 hit song "Even If," which, like "I Can Only Imagine," achieved significant success.
