As the seventh month since his wife’s passing ticks away, Benjamin Mee is wrestling with the overwhelming grief that now defines his everyday existence. With his 14-year-old son Dylan recently expelled from school, the harsh reality of their untenable situation forces Benjamin to confront the void left by Katherine’s absence. Each moment feels like a painful echo of her departure, pushing him to seek a path that leads to renewal and a fresh start.
This search for a new beginning unfolds as Benjamin, along with his 7-year-old daughter Rosie and their realtor Mr. Stevens, sets out to find a new home. Their journey takes an unexpected turn when they discover an old property that ignites Rosie's excitement, especially at the thought of peacocks gracing the grounds. Despite Mr. Stevens’ doubts about the property, Benjamin's heart sees its potential and he boldly decides to claim it, deeming it “perfect” – a choice that sets him on an unexpected path of self-discovery.
The urge for change also brings forth criticism from Benjamin's accountant brother Duncan, who is less than enthusiastic about the planned purchase. Nevertheless, as Benjamin watches Rosie play joyfully among the peacocks, he makes the audacious choice to buy not just the home but the dilapidated zoo attached to it, which has been closed for years.
Meanwhile, Dylan, struggling with the idea of leaving his friends behind, immerses himself in art to cope with the upheaval. Duncan attempts to dissuade him and cautions that their new venture might be destined for failure, but Benjamin remains steadfast in his hope for brighter days ahead.
As the rebuilding of the zoo begins under the watchful eye of Kelly Foster, they are confronted by Walter Ferris, a strict USDA inspector, who presents a daunting list of repairs needed, costing over $100,000. With finances looming large, Benjamin grapples with the harsh truth that keeping the zoo operational may not be feasible.
Morale sinks among the staff as rumors swirl about a potential sale that could spell the end for the zoo. On the lighter side, Dylan finds comfort in his budding friendship with Lily, Kelly’s cousin, who harbors a crush on him. However, this connection is tested when Lily learns about the family’s possible departure, causing her distress.
Amidst these emotional and financial trials, Benjamin unexpectedly uncovers an investment account left by Katherine, providing a glimmer of hope. While Duncan suggests he use the funds to sever ties and start afresh, Benjamin instead decides to invest in revitalizing the zoo, driven by a renewed sense of purpose.
Determined to change their circumstances, Benjamin sets out to not only restore the zoo but also to mend his family’s fractured spirits, seeking closure and redemption along the way. The escalating tensions between Dylan and Benjamin culminate in an emotional confrontation, which ultimately leads to a heartfelt reconciliation. Dylan shares his feelings for Lily, inspiring Benjamin to impart his life philosophy: that just 20 seconds of audacious courage can pave the way for greatness. Guided by this wisdom, Benjamin acknowledges that Katherine will always be a part of him, while Dylan finds the courage to express his feelings to Lily, rekindling their attachment.
As the zoo's grand opening approaches, anxiety fills the air as everyone awaits the outcome of Ferris’ inspection. Their fears are compounded by news of an impending rainstorm that threatens to undo their hard work. However, the skies unexpectedly clear just in time for the opening, though they face an unsettling silence as no visitors appear. Disappointment turns to elation as a fallen tree creates a makeshift entryway, allowing crowds of curious guests to flood in.
In the whirlwind of activity, Benjamin and Kelly share a tender moment in a secluded shed, igniting a blossoming connection. Later, the family visits the restaurant where Benjamin first won Katherine’s heart, prompting him to recount the moment he dared to approach her, spurred by 20 seconds of insane courage. He reflects on his disbelief that such an incredible woman would even look his way, to which he vividly remembers her simple yet profound response: “Why not?” This serves as a touching reminder of the unpredictability and beauty of love and life.
